Section 2Project Information2.1 Project and Site DescriptionThis project constructs municipal water well (#11) on the north side of Hwy 246 near its intersection with theSanta Ynez River, to provide additional water supply to the City of Lompoc. A transmission water main will beconstructed, in conjunction with the well, to pipe water from the well site north to Riverside Dr., Pine St., 3 rd St.and North Ave. and then to connect to a water main on North Ave. The project is 2.3 acres and includesdrilling of the well, construction of a pump building, an electrical building, a CMU wall surrounding wellstructures, a driveway, drainage improvements, a transmission water main line, landscaping and mitigationplanting. The well portion of the project is defined as a traditional project while the transmission water main isdefined as a linear project. Requirements for both project types are covered under this SWPPP.2.2 Vicinity MapA vicinity map is provided in Figure 1.Figure 1. Vicinity Map of Project2.3 Unique Site FeaturesThe well site and portion of the transmission water main are within an environmentally sensitive area, adjacentto the Santa Ynez River and its riparian zone. Though characterized by upland plants in the area ofconstruction, the site drains directly to the Santa Ynez River overland through sheet flow. The transmissionwater main, access drive and other improvements are located within the 100-year flood plain. Any portion ofthe well site which is located within the 100-year flood plain will be flood-proofed and constructed at anelevation which meets the requirements of the City’s Flood Ordinance. The project has been designed tominimize the impact to the Santa Ynez River and its riparian zone. Mitigation measures have been applied toaddress potential biological impacts.The site of the proposed Well 11 is relatively flat, dropping off to the east toward the river bank. Run-onoccurs in the area of the access drive and a culvert is proposed to direct the run-on through the site in aMunicipal Water Well No. 11 and Transmission Water Main – SWPPP July 20, 2010Page 6

proposed drainage swale. Run-on also occurs along the length of the transmission water main location,through sheet flow heading towards the Santa Ynez River. At the north end of the proposed transmissionwater main alignment, run-on occurs from a storm drain which terminates in a large, relatively steep gully,through which the transmission water main will be placed.The site is relatively flat to very gently sloping and drains by sheet flow. There is no run-on to the well site.Soils at the well site consist of layered sands that were moist to wet with a medium dense to denseconsistency. A isolated layer of silt soil exists at 14 -19 ft below the ground surface and the silt was moist andvery stiff. Groundwater was encoutered at a depth of 38 ft below the ground surface.The project is subject to requirements of the California Department of Fish and Game. The contractor shall beresponsible for ensuring compliance with all CDFG requirements and with the specific mitigation measures ofthe project. The letter from the California Department of Fish and Game, the Notification of StreambedAlteration Agreement and its attachments are provided in Appendix J2.4 SWPPP ObjectivesThis SWPPP has been designed to address the following objectives:1. All pollutants and their sources, including sources of sediment associated with construction,construction site erosion and all other activities associated with construction activity are controlled;2. Where not otherwise required to be under a Regional Water Board permit, all non-storm waterdischarges are identified and either eliminated, controlled, or treated;3. Site BMPs are effective and result in the reduction or elimination of pollutants in storm waterdischarges and authorized non-storm water discharges from construction activity to the best availabletechnology economically achievable (BAT) / best conventional pollutant control technology (BCT)standard;4. Calculations and design details as well as Best Management Practices (BMPs) controls for site run-onare complete and correct, and5. Stabilization BMPs installed to reduce or eliminate pollutants after construction are completed.2.5 Stormwater Run-on and Runoff from Offsite AreasRun-on is considered insignificant to the linear project and is received on site as sheet flow. The well site isapproximately 2 feet above existing grade and will not have any run–on. Runoff will also be minimal. The wellsite is less than 0.5 acre and runoff is directed to an existing roadside ditch. The disturbed area for thetransmission water lines site is approximately 30 ft wide in unpaved areas and approximately 3’ wide in pavedareas. On unpaved areas, it is adjacent to stable vegetation and low gradients. On paved areas, water will beconveyed by the existing municipal storm drain system. There are no calculations.2.6 Risk AssessmentThe General Permit establishes three levels of risk possible for a construction site. Risk is calculated in twoparts: 1) Project Sediment Risk, and 2) Receiving Water Risk. The site's sediment risk and receiving water riskwas evaluated for the period of soil exposure (i.e. grading and site stabilization) using the methodology inAppendix 1 of the General Permit. This project is a combined traditional and linear project. The higher risklevel of Risk Level 2 (Type 2 LUP) was chosen to represent the entire site.Municipal Water Well No. 11Sediment Risk: MediumThe RUSLE equation was used through the Rainfall Erositivity Factor Calculator and the GIS Map Method todetermine soil risk. The online rainfall erosivity factor calculator (R) is based on soil erosivity and constructionscheduling. It was determined that the R factor is 24.62. Using the GIS Map Method and soil characteristicsdescribed in the Soils Engineering Report (2009), the project site lies in the KLS risk category of 1.0.Therefore, the project will contribute less than 75 tons/acre of sediment and has a medium sediment risk.Municipal Water Well No. 11 and Transmission Water Main – SWPPP July 20, 2010Page 7

Receiving Water: HighThe Santa Ynez River is on the impaired waterbody 303d list for sedimentation/siltation, and has beneficialuses of Cold water Fishery, Migratory, and Spawning. Based on these characteristics, the site has a highreceiving water risk.In accordance with the chart below, the project was determined to have a combined Level 2 Risk based on itssediment (low) and receiving water (high) characteristics. A copy of the Risk Assessment is provided inAppendix D.The General Permit requires visual monitoring at all sites, and effluent water quality at all Risk Level 2 & 3.Section 4 elaborates on the required monitoring for this project. This SWPPP is designed to adhere to RiskLevel 2 requirements as established in Attachment D of the General Permit.Transmission Water MainThe Transmission Water Main will be installed primarily along existing paved roads. In addition, disturbedareas will be returned to pre-construction conditions at project completion. Using the LUP Project TypeDetermination Flow Chart in Attachment A.1 of the Permit, the project is considered a Type 1 LUP. However,because this is a combined SWPPP the higher risk level of the two portions of the project was utilized. Type 2LUP requirements will be met for the linear portion of the project.2.7 Construction ScheduleThe project is anticipated to start in the fall of 2010 and be completed prior to the rainy season.Contract Award 01/01/2011Site Preparation and Grubbing 01/01/2011Implement Temporary Erosion and Sediment Control BMPs 01/08/2011Clearing and Grading 01/10/2011Well Drilling 01/15/2011Electrical conduit/ subgrade preparation 01/27/2011Transmission Water Main Line 02/20/2011PCC and Drainage 02/27/2011AC Paving Operations 02/27/11Slope Stabilization 08/10/2011Project Accepted 08/15/20112.8 Potential Construction Site Pollutant SourcesThe following is a list of construction materials which will be used and activities that will be performed thathave the potential to contribute pollutants off-site:• Clearing, Grubbing, Trenching and Grading Operations (slopes, pads, driveway and pipeline)• Base and AC Pavement Placement (driveway and pipeline)• PCC (curbs and pads)• Vehicle fluids, including oil, grease, petroleum and coolants (from construction equipment)• Trash (from construction personnel)Municipal Water Well No. 11 and Transmission Water Main – SWPPP July 20, 2010Page 8

A qualifying rainevent is defined as any event producing precipitation of ½ inch or more within a 48 hour or greater period. Arain gage should be installed on-site, if possible.Monitoring locations provide clear views of BMPs, disturbed areas and extend through the entire site.Dischargers must maintain on-site records of all visual observations, personnel performing the observations,observation dates, weather conditions, locations observed, and corrective actions taken in response to theobservations. The Construction Site Monitoring Checklists (Appendix F) should be used to track all monitoringactivities.At the water main site only, inspections may be discontinued in non-active construction areas where soildisturbingactivities are completed and final soil stabilization is achieved.Municipal Water Well No. 11 and Transmission Water Main – SWPPP July 20, 2010Page 13

Figure 2. Overview of Monitoring LocationsSection 1Section 2Municipal Water Well No. 11 and Transmission Water Main – SWPPP July 20, 2010Page 14

Section 34.1 Visual Monitoring/ InspectionAll storm water monitoring must be completed within two (2) business days of each qualifying rain event atidentified locations. Appendix C shows the monitoring locations.BMP InspectionThe purpose of these inspections is to identify BMPs that:• Need maintenance to operate effectively;• Failed; or• Could fail to operate as intended.If deficiencies are identified during BMP inspections, repairs or design changes to BMPs mustbe initiated within 72 hours of identification and need to be completed as soon as possible.All BMP inspections must be documented on an inspection checklist (Appendix F).Storm water InspectionDischargers must conduct a pre-storm event inspection of:• All storm water drainage areas to identify and resolve prior to the storm event, any spills, leaks, oruncontrolled pollutant sources• All BMPs to identify proper implementation• Any storm water storage and containment areas to detect and remedy leaks if foundDischargers must conduct a post-storm event inspection within two business days (48 hours)to identify whether:(1) BMPs were adequately designed, implemented, and effective, and(2) If any additional BMPs necessary (and amend the SWPPP accordingly).Municipal Water Well No. 11 and Transmission Water Main – SWPPP July 20, 2010Page 15

Visual inspection shall be made of any stored or contained storm water derived from and discharged after arain event that is producing ½ inch or more at the time of discharge. If discharge due to additional precipitationis expected to occur after business hours, visual inspection shall take place during operating hours.For the linear portion of the project, photographs of the site must be taken before, during and after stormevents during inspections, and submitted through SMARTS once every three rain events.Non-stormwater InspectionSee Section 4.34.2 Rain Event Action PlansRain Event Action Plans (REAP) are required for each construction phase at the well site only. Linear projectsdo not require a REAP. The REAP is designed to protect all exposed portions of project sites and to ensurethat the discharger has adequate materials, staff, and time to implement erosion and sediment controlmeasures that are intended to reduce the amount of sediment and other pollutants that could be generatedduring the rain event. A REAP template is included in SWPPP Appendix G.Construction phases for this project include:• Grading and Land Development• Street and Utilities• Vertical Construction• Site StabilizationThe SWPPPM shall develop additional REAPs for the project sites where construction activities are indefinitelyhalted or postponed.The SWPPPM must develop the REAP 48-hours in advance of any precipitation event forecast to have a 50%or greater chance of producing precipitation in the project area. A printed copy of the precipitation forecastshall be obtained by the QSP from the National Weather Service Forecast Office. The REAP must be on siteand be implemented 24 hours in advance of any the predicted precipitation event. A paper copy of each REAPshall remain on-site during the full term of the project.4.3 Non-Storm water Discharge MonitoringQuarterly non-storm water discharge monitoring will include the visual inspection of each drainage area duringdaylight hours for the presence of non-storm water discharges and their sources in April - June and July –September quarters. If non-storm water is discharged off site, the effluent must be sampled. Quarterlymonitoring should be recorded on Construction Site Monitoring Checklists in Appendix F.Potential non-stormwater discharges within this project include:• Vehicle and equipment fueling and maintenance• Concrete mixingQuarterly inspections need to include each drainage area of the project and document:• Presence or indications of unauthorized and authorized non-storm water discharges and their sources;• Pollutant characteristics of the non-storm water discharge (floating and suspended material, sheen,discoloration, turbidity, odor, etc;• Personnel performing the observations;• Dates and approximate time each drainage area and non-stormwater discharge was observed; and• Response taken to observations.4.4 Water Quality Sampling and AnalysisThe project is required to collect samples of:• runoff for non-visible pollutants in the event of a BMP failure, breach or spill• runoff and contained water for pH and turbidity• non-stormwater dischargeMunicipal Water Well No. 11 and Transmission Water Main – SWPPP July 20, 2010Page 16

Sampling personnel will collect storm water grab samples at discharge locations according to proceduresoutlined in Section 4.5 Quality Assurance and Quality Control. Monitoring checklists are in Appendix F.Appendix C shows the monitoring locations for all monitoring.Sampling is not required outside of scheduled business hours or under dangerous conditions. An explanationof why samples were not taken will be included with on-site inspection documents.Storm water SamplingIt is expected that the site will have minimal sheet flow. For a qualifying rain event, a minimum of 3 samplesper day will be collected, if there is runoff from the site that originates in the project area. It should be ensuredthat storm water discharge collected and observed represent the effluent in each drainage area, based onvisual observation of the water and upstream conditions.Effluent will be analyzed for pH and turbidity and non-visible pollutant parameters (if applicable). Analysis ofpH will be performed on-site with a calibrated pH meter or a pH test kit. pH analysis only needs to occur whenhigh pH activities (like use of concrete, lime, gypsum) are undertaken during predicted rain (like use ofconcrete, lime, gypsum). Turbidity analysis will be performed using a calibrated turbidity meter either on-site orat an accredited lab.Risk Level 2 projects are subject to the following Numeric Action Levels (NALs):• pH 6.5 – 8.5• Turbidity 250 NTURun-on will be monitored only if there is reason to believe run-on may contribute to an exceedance of NALs.In the event that the storm event average of the samples exceeds an applicable NAL, Risk Level 2 dischargersmust electronically submit all storm event sampling results to the SWRCB’s SMARTS no later than 10 daysafter the conclusion of the storm event. In addition, the RWQCBs may request the submittal of an NALExceedance Report. The discharger must certify each NAL Exceedance Report in accordance with theGeneral Permit’s Special Provisions for Construction Activity.Non-Visible Pollutant SamplingIf there is a breach, spill or BMP failure, runoff potentially affected by the non-visible pollutants will be sampledwithin the first two hours of discharge. Ensure the grab samples collected of stored or contained storm waterare from discharges subsequent to a qualifying rain event (That which produces ½ inch or more at the time ofdischarge.), and that water samples taken are large enough to characterize the site conditions. Collect one ormore samples during any breach, malfunction, leak or spill observed during a visual inspection, which couldresult in the discharge of pollutants to surface waters that would not be visually detectable in storm water.Also, collect samples that have not come in contact with the disturbed soil or the materials stored or used onsitefor comparison with the discharge sample.Samples will be analyzed for all applicable non-visible pollutant parameters – indicating the presence ofpollutants identified in the pollutant source assessment required. The SWPPP shall be modified to identify anyadditional pollutants found.It is important to note that covered construction materials or those that are in their final constructed form, donot need to be monitored. Materials that are stored exposed to precipitation and may generate runoff need tobe considered for non-visible pollutant monitoring. Appendix H provides further guidance.Non-Storm water SamplingIf non-storm water is discharged off site, the effluent must be sampled. All non-storm water sample analysesshould be conducted by a state certified laboratory.Municipal Water Well No. 11 and Transmission Water Main – SWPPP July 20, 2010Page 17

4.5 Quality Assurance and Quality ControlThe SWPPPM is responsible for non-storm water and storm water visual observations, sampling and analysis,and for ensuring full compliance with the permit and implementation of all elements of the SWPPP.Prior to the rainy season, all sampling personnel and alternates will review the Monitoring Plan. Qualificationsof designated personnel describing environmental sampling training and experience are provided in AppendixB. Sampling personnel will be designated and trained to collect, maintain and ship samples in accordance withthe Surface Water Ambient Monitoring Program’s (SWAMP) 2008 Quality Assurance Program Plan (QAPP)(http://www.swrcb.ca.gov/water_issues/programs/swamp/tools.shtml#qa).Supplies and StorageAn adequate stock of supplies and equipment for monitoring pH, turbidity, and non-visible pollutants will beavailable on the project site or provided by the identified state certified laboratory (Appendix F) prior to asampling event.Monitoring supplies and equipment will be stored in a cool-temperature environment that will not come intocontact with rain or direct sunlight. Sampling personnel will be available to collect samples in accordance withthe sampling schedule.Supplies maintained at the project site will include, but will not be limited to, surgical gloves, sample collectionequipment, coolers, appropriate number and volume of sample bottles, identification labels, re-sealablestorage bags, paper towels, personal rain gear, ice, Sampling Activity Log forms, and Chain of Custody (COC)forms.The Contractor will obtain and maintain the field-testing instruments, as identified below for analyzing samplesin the field by sampling personnel. Safety practices for sample collection will be followed in accordance withthe Contactor’s health and safety plan for the project (Appendix F).Field InstrumentsFor samples collected for field analysis, collection, analysis and equipment calibration will be in accordancewith the field instrument manufacturer’s specifications.• The instrument(s) will be maintained in accordance with manufacturer’s instructions.• The instrument(s) will be calibrated before each sampling and analysis event.• Maintenance and calibration records will be maintained with the SWPPP.Water Quality Constituent Analytical Method, Minimum Detection Limits, Sample Size and ContainerRequirements shall be as follows:Sample Collection and Handling ProceduresAll sampling and sample preservation must be in accordance with the current edition of Standard Methods forthe Examination of Water and Wastewater (American Public Health Association).To maintain sample integrity and prevent cross-contamination, sampling collection personnel will:• Wear a clean pair of surgical gloves prior to the collection and handling of each sample at eachlocation.• Not contaminate the inside of the sample bottle by not allowing it to come into contact with anymaterial other than the water sample.Municipal Water Well No. 11 and Transmission Water Main – SWPPP July 20, 2010Page 18

• Discard sample bottles or sample lids that have been dropped onto the ground prior to samplecollection.• Not leave the cooler lid open for an extended period of time once samples are placed inside.• Not touch the exposed end of a sampling tube, if applicable.• Avoid allowing rainwater to drip from rain gear or other surfaces into sample bottles.• Not eat, smoke, or drink during sample collection.• Not sneeze or cough in the direction of an open sample bottle.• Minimize the exposure of the samples to direct sunlight, as sunlight may cause biochemicaltransformation of the sample to take place.• Decontaminate sampling equipment prior to sample collection using a TSP-soapy water wash, distilledwater rinse, and final rinse with distilled water.• Dispose of decontamination water/soaps appropriately; i.e., not discharge to the storm drain system orreceiving water.Immediately following collection, samples for field analysis will be tested in accordance with the fieldinstrument manufacturer’s instructions and results recorded on the Construction Site Monitoring Checklists,provided in Appendix F. Any samples provided to a lab will be provided within 48 hours and use only thesample bottle provided by the lab.Uncontaminated sample will be compared to the samples with potential contamination.For an initial verification of laboratory or field analysis, duplicate samples will be collected at a rate of 10percent or 1 duplicate per sampling event. The duplicate sample will be collected, handled, and analyzedusing the same protocols as primary samples, and will be collected where contaminants are likely, and not onthe upstream sample. A duplicate sample will be collected immediately after the primary sample has beencollected. Duplicate samples will not influence any evaluations or conclusions; however, they will be used as acheck on state certified laboratory quality assurance.Visible PollutantsGrab samples will be collected and preserved in accordance with the methods identified above. Onlypersonnel trained in proper water quality sampling will collect samples.Samples will not be collected directly from ponded, sluggish, or stagnant water. Samples will be collectedusing one of the following methods:• Placing a sample bottle directly into the collected flow in or near the main current upstream ofsampling personnel, and allowing the sample bottle to fill completely; OR,• Placing a decontaminated or ‘sterile’ bailer or other ‘sterile’ collection device in or near the maincurrent to collect the sample, and then transferring the collected water to appropriate sample bottles,allowing the sample bottles to fill completely. Run-on samples, if applicable, will be collected to identifypotential turbidity that originates off the project site and contributes to direct discharges from theconstruction site to the Santa Ynez River. Run-on samples will be collected down gradient and withinclose proximity of the point of run-on to the project by pooling or ponding water and allowing theponded water to spill over into sample bottles directly in the stream of water.Non-Visible PollutantsNon-visible pollutants may include those from:• Concrete Wastes (lighting foundations, concrete v-ditch and ADA curb ramp)• Vehicle fluids, including oil, grease, petroleum and coolants (from construction equipment)• Vehicle and equipment fueling• Sanitary Waste• Landscaping products• Soil stabilization productsMunicipal Water Well No. 11 and Transmission Water Main – SWPPP July 20, 2010Page 19

In the event that sampling is needed, all non-storm water sample analyses will be sent to a state certifiedlaboratory. Use Appendix H as a guide.Sample Documentation ProceduresAll original data documented on sample bottle identification labels, Chain of Custody forms, Sampling ActivityLogs, and Inspection Checklists will be recorded using waterproof ink. These will be considered accountabledocuments. If an error is made on an accountable document, the individual will make corrections by liningthrough the error and entering the correct information. The erroneous information will not be obliterated. Allcorrections will be initialed and dated.

12Sediment Risk Factor WorksheetA) R FactorA B CEntry345678Analyses of data indicated that when factors other than rainfall are held constant, soil loss is directly proportional to arainfall factor composed of total storm kinetic energy (E) times the maximum 30-min intensity (I30) (Wischmeier andSmith, 1958). The numerical value of R is the average annual sum of EI30 for storm events during a rainfall record ofat least 22 years. "Isoerodent" maps were developed based on R values calculated for more than 1000 locations in theWestern U.S. Refer to the link below to determine the R factor for the project site.http://cfpub.epa.gov/npdes/stormwater/LEW/lewCalculator.cfmB) K Factor (weighted average, by area, for all site soils)R Factor ValueThe soil-erodibility factor K represents: (1) susceptibility of soil or surface material to erosion, (2) transportability of thesediment, and (3) the amount and rate of runoff given a particular rainfall input, as measured under a standardcondition. Fine-textured soils that are high in clay have low K values (about 0.05 to 0.15) because the particles areresistant to detachment. Coarse-textured soils, such as sandy soils, also have low K values (about 0.05 to 0.2)because of high infiltration resulting in low runoff even though these particles are easily detached. Medium-texturedsoils, such as a silt loam, have moderate K values (about 0.25 to 0.45) because they are moderately susceptible toparticle detachment and they produce runoff at moderate rates. Soils having a high silt content are especiallysusceptible to erosion and have high K values, which can exceed 0.45 and can be as large as 0.65. Silt-size particlesare easily detached and tend to crust, producing high rates and large volumes of runoff. Use Site-specific data mustbe submitted.Site-specific K factor guidance24.629K Factor Value1101112C) LS Factor (weighted average, by area, for all slopes)The effect of topography on erosion is accounted for by the LS factor, which combines the effects of a hillslope-lengthfactor, L, and a hillslope-gradient factor, S. Generally speaking, as hillslope length and/or hillslope gradient increase,soil loss increases. As hillslope length increases, total soil loss and soil loss per unit area increase due to theprogressive accumulation of runoff in the downslope direction. As the hillslope gradient increases, the velocity anderosivity of runoff increases. Use the LS table located in separate tab of this spreadsheet to determine LS factors.Estimate the weighted LS for the site prior to construction.LS Table1314151617181920LS Factor ValueWatershed Erosion Estimate (=RxKxLS) in tons/acreSite Sediment Risk FactorLow Sediment Risk: < 15 tons/acreMedium Sediment Risk: >=15 and = 75 tons/acre24.62Medium0

OrderSTATE WATER RESOURCES CONTROL BOARDORDER NO. 2009-0009-DWQNATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEMGENERAL PERMIT NO. CAS000002WASTE DISCHARGE REQUIREMENTSFORDISCHARGES OF STORM WATER RUNOFF ASSOCIATED WITHCONSTRUCTION AND LAND DISTURBANCE ACTIVITIESI. FINDINGSA. General FindingsThe State Water Resources Control Board (State Water Board) finds that:1. The federal Clean Water Act (CWA) prohibits certain discharges ofstorm water containing pollutants except in compliance with a NationalPollutant Discharge Elimination System (NPDES) permit (Title 33United States Code (U.S.C.) §§ 1311 and 1342(p); also referred to asClean Water Act (CWA) §§ 301 and 402(p)). The U.S. EnvironmentalProtection Agency (U.S. EPA) promulgates federal regulations toimplement the CWA’s mandate to control pollutants in storm waterrunoff discharges. (Title 40 Code of Federal Regulations (C.F.R.)Parts 122, 123, and 124). The federal statutes and regulations requiredischarges to surface waters comprised of storm water associated withconstruction activity, including demolition, clearing, grading, andexcavation, and other land disturbance activities (except operationsthat result in disturbance of less than one acre of total land area andwhich are not part of a larger common plan of development or sale), toobtain coverage under an NPDES permit. The NPDES permit mustrequire implementation of Best Available Technology EconomicallyAchievable (BAT) and Best Conventional Pollutant Control Technology(BCT) to reduce or eliminate pollutants in storm water runoff. TheNPDES permit must also include additional requirements necessary toimplement applicable water quality standards.2. This General Permit authorizes discharges of storm water associatedwith construction activity so long as the dischargers comply with allrequirements, provisions, limitations and prohibitions in the permit. Inaddition, this General Permit regulates the discharges of storm waterassociated with construction activities from all LinearUnderground/Overhead Projects resulting in the disturbance of greaterthan or equal to one acre (Attachment A).2009-0009-DWQ 1 September 02, 2009

Order3. This General Permit regulates discharges of pollutants in storm waterassociated with construction activity (storm water discharges) to watersof the United States from construction sites that disturb one or moreacres of land surface, or that are part of a common plan ofdevelopment or sale that disturbs more than one acre of land surface.4. This General Permit does not preempt or supersede the authority oflocal storm water management agencies to prohibit, restrict, or controlstorm water discharges to municipal separate storm sewer systems orother watercourses within their jurisdictions.5. This action to adopt a general NPDES permit is exempt from theprovisions of Chapter 3 of the California Environmental Quality Act(CEQA) (Public Resources Code Section 21100, et seq.), pursuant toSection 13389 of the California Water Code.6. Pursuant to 40 C.F.R. § 131.12 and State Water Board Resolution No.68-16, 1 which incorporates the requirements of § 131.12 whereapplicable, the State Water Board finds that discharges in compliancewith this General Permit will not result in the lowering of water qualitystandards, and are therefore consistent with those provisions.Compliance with this General Permit will result in improvements inwater quality.7. This General Permit serves as an NPDES permit in compliance withCWA § 402 and will take effect on July 1, 2010 by the State WaterBoard provided the Regional Administrator of the U.S. EPA has noobjection. If the U.S. EPA Regional Administrator objects to itsissuance, the General Permit will not become effective until suchobjection is withdrawn.8. Following adoption and upon the effective date of this General Permit,the Regional Water Quality Control Boards (Regional Water Boards)shall enforce the provisions herein.9. Regional Water Boards establish water quality standards in BasinPlans. The State Water Board establishes water quality standards invarious statewide plans, including the California Ocean Plan. U.S.EPA establishes water quality standards in the National Toxic Rule(NTR) and the California Toxic Rule (CTR).1 Resolution No. 68-16 generally requires that existing water quality be maintained unless degradation isjustified based on specific findings.2009-0009-DWQ 2 September 02, 2009

Order10. This General Permit does not authorize discharges of fill or dredgedmaterial regulated by the U.S. Army Corps of Engineers under CWA §404 and does not constitute a waiver of water quality certification underCWA § 401.11. The primary storm water pollutant at construction sites is excesssediment. Excess sediment can cloud the water, which reduces theamount of sunlight reaching aquatic plants, clog fish gills, smotheraquatic habitat and spawning areas, and impede navigation in ourwaterways. Sediment also transports other pollutants such asnutrients, metals, and oils and greases.12. Construction activities can impact a construction site’s runoff sedimentsupply and transport characteristics. These modifications, which canoccur both during and after the construction phase, are a significantcause of degradation of the beneficial uses established for waterbodies in California. Dischargers can avoid these effects throughbetter construction site design and activity practices.13. This General Permit recognizes four distinct phases of constructionactivities. The phases are Grading and Land Development Phase,Streets and Utilities Phase, Vertical Construction Phase, and FinalLandscaping and Site Stabilization Phase. Each phase has activitiesthat can result in different water quality effects from different waterquality pollutants. This General Permit also recognizes inactiveconstruction as a category of construction site type.14. Compliance with any specific limits or requirements contained in thisGeneral Permit does not constitute compliance with any otherapplicable requirements.15. Following public notice in accordance with State and Federal laws andregulations, the State Water Board heard and considered all commentsand testimony in a public hearing on 06/03/2009. The State WaterBoard has prepared written responses to all significant comments.16. Construction activities obtaining coverage under the General Permitmay have multiple discharges subject to requirements that are specificto general, linear, and/or active treatment system discharge types.17. The State Water Board may reopen the permit if the U.S. EPA adoptsa final effluent limitation guideline for construction activities.2009-0009-DWQ 3 September 02, 2009

OrderB. Activities Covered Under the General Permit18. Any construction or demolition activity, including, but not limited to,clearing, grading, grubbing, or excavation, or any other activity thatresults in a land disturbance of equal to or greater than one acre.19. Construction activity that results in land surface disturbances of lessthan one acre if the construction activity is part of a larger commonplan of development or the sale of one or more acres of disturbed landsurface.20. Construction activity related to residential, commercial, or industrialdevelopment on lands currently used for agriculture including, but notlimited to, the construction of buildings related to agriculture that areconsidered industrial pursuant to U.S. EPA regulations, such as dairybarns or food processing facilities.21. Construction activity associated with Linear Underground/OverheadUtility Projects (LUPs) including, but not limited to, those activitiesnecessary for the installation of underground and overhead linearfacilities (e.g., conduits, substructures, pipelines, towers, poles, cables,wires, connectors, switching, regulating and transforming equipmentand associated ancillary facilities) and include, but are not limited to,underground utility mark-out, potholing, concrete and asphalt cuttingand removal, trenching, excavation, boring and drilling, access roadand pole/tower pad and cable/wire pull station, substation construction,substructure installation, construction of tower footings and/orfoundations, pole and tower installations, pipeline installations,welding, concrete and/or pavement repair or replacement, andstockpile/borrow locations.22. Discharges of sediment from construction activities associated with oiland gas exploration, production, processing, or treatment operations ortransmission facilities. 223. Storm water discharges from dredge spoil placement that occuroutside of U.S. Army Corps of Engineers jurisdiction (upland sites) andthat disturb one or more acres of land surface from construction activityare covered by this General Permit. Construction sites that intend todisturb one or more acres of land within the jurisdictional boundaries ofa CWA § 404 permit should contact the appropriate Regional WaterBoard to determine whether this permit applies to the site.2 Pursuant to the Ninth Circuit Court of Appeals’ decision in NRDC v. EPA (9th Cir. 2008) 526 F.3d 591, andsubsequent denial of the U.S. EPA’s petition for reconsideration in November 2008, oil and gas constructionactivities discharging storm water contaminated only with sediment are no longer exempt from the NPDESprogram.2009-0009-DWQ 4 September 02, 2009

OrderC. Activities Not Covered Under the General Permit24. Routine maintenance to maintain original line and grade, hydrauliccapacity, or original purpose of the facility.25. Disturbances to land surfaces solely related to agricultural operationssuch as disking, harrowing, terracing and leveling, and soil preparation.26. Discharges of storm water from areas on tribal lands; construction ontribal lands is regulated by a federal permit.27. Construction activity and land disturbance involving discharges ofstorm water within the Lake Tahoe Hydrologic Unit. The LahontanRegional Water Board has adopted its own permit to regulate stormwater discharges from construction activity in the Lake TahoeHydrologic Unit (Regional Water Board 6SLT). Owners of constructionsites in this watershed must apply for the Lahontan Regional WaterBoard permit rather than the statewide Construction General Permit.28. Construction activity that disturbs less than one acre of land surface,and that is not part of a larger common plan of development or the saleof one or more acres of disturbed land surface.29. Construction activity covered by an individual NPDES Permit for stormwater discharges.30. Discharges from small (1 to 5 acre) construction activities with anapproved Rainfall Erosivity Waiver authorized by U.S. EPA Phase IIregulations certifying to the State Board that small construction activitywill occur only when the Rainfall Erosivity Factor is less than 5 (“R” inthe Revised Universal Soil Loss Equation).31. Landfill construction activity that is subject to the Industrial GeneralPermit.32. Construction activity that discharges to Combined Sewer Systems.33. Conveyances that discharge storm water runoff combined withmunicipal sewage.34. Discharges of storm water identified in CWA § 402(l)(2), 33 U.S.C. §1342(l)(2).2009-0009-DWQ 5 September 02, 2009

Order35. Discharges occurring in basins that are not tributary or hydrologicallyconnected to waters of the United States (for more information contactyour Regional Water Board).D. Obtaining and Modifying General Permit Coverage36. This General Permit requires all dischargers to electronically file allPermit Registration Documents (PRDs), Notices of Termination (NOT),changes of information, annual reporting, and other compliancedocuments required by this General Permit through the State WaterBoard’s Storm water Multi-Application and Report Tracking System(SMARTS) website.37. Any information provided to the Regional Water Board shall complywith the Homeland Security Act and any other federal law thatconcerns security in the United States; any information that does notcomply should not be submitted.38. This General Permit grants an exception from the Risk Determinationrequirements for existing sites covered under Water Quality Orders No.99-08-DWQ, and No. 2003-0007-DWQ. For certain sites, addingadditional requirements may not be cost effective. Construction sitescovered under Water Quality Order No. 99-08-DWQ shall obtain permitcoverage at the Risk Level 1. LUPs covered under Water QualityOrder No. 2003-0007-DWQ shall obtain permit coverage as a Type 1LUP. The Regional Water Boards have the authority to require RiskDetermination to be performed on sites currently covered under WaterQuality Orders No. 99-08-DWQ and No. 2003-0007-DWQ where theydeem it necessary. The State Water Board finds that there are twocircumstances when it may be appropriate for the Regional WaterBoards to require a discharger that had filed an NOI under State WaterBoard Order No. 99-08-DWQ to recalculate the site’s risk level. Thesecircumstances are: (1) when the discharger has a demonstratedhistory of noncompliance with State Water Board Order No. 99-08-DWQ or; (2) when the discharger’s site poses a significant risk ofcausing or contributing to an exceedance of a water quality standardwithout the implementation of the additional Risk Level 2 or 3requirements.E. Prohibitions39. All discharges are prohibited except for the storm water and non-stormwater discharges specifically authorized by this General Permit oranother NPDES permit. Non-storm water discharges include a widevariety of sources, including improper dumping, spills, or leakage fromstorage tanks or transfer areas. Non-storm water discharges may2009-0009-DWQ 6 September 02, 2009

Ordercontribute significant pollutant loads to receiving waters. Measures tocontrol spills, leakage, and dumping, and to prevent illicit connectionsduring construction must be addressed through structural as well asnon-structural Best Management Practices (BMPs) 3 . The State WaterBoard recognizes, however, that certain non-storm water dischargesmay be necessary for the completion of construction.40. This General Permit prohibits all discharges which contain ahazardous substance in excess of reportable quantities established in40 C.F.R. §§ 117.3 and 302.4, unless a separate NPDES Permit hasbeen issued to regulate those discharges.41. This General Permit incorporates discharge prohibitions contained inwater quality control plans, as implemented by the State Water Boardand the nine Regional Water Boards.42. Pursuant to the Ocean Plan, discharges to Areas of Special BiologicalSignificance (ASBS) are prohibited unless covered by an exceptionthat the State Water Board has approved.43. This General Permit prohibits the discharge of any debris 4 fromconstruction sites. Plastic and other trash materials can causenegative impacts to receiving water beneficial uses. The State WaterBoard encourages the use of more environmentally safe,biodegradable materials on construction sites to minimize the potentialrisk to water quality.F. Training44. In order to improve compliance with and to maintain consistentenforcement of this General Permit, all dischargers are required toappoint two positions - the Qualified SWPPP Developer (QSD) and theQualified SWPPP Practitioner (QSP) - who must obtain appropriatetraining. Together with the key stakeholders, the State and RegionalWater Boards are leading the development of this curriculum through acollaborative organization called The Construction General Permit(CGP) Training Team.45. The Professional Engineers Act (Bus. & Prof. Code section 6700, etseq.) requires that all engineering work must be performed by aCalifornia licensed engineer.3 BMPs are scheduling of activities, prohibitions of practices, maintenance procedures, and othermanagement practices to prevent or reduce the discharge of pollutants to waters of the United States. BMPsalso include treatment requirements, operating procedures, and practice to control site runoff, spillage orleaks, sludge or waste disposal, or drainage from raw material storage.4 Litter, rubble, discarded refuse, and remains of destroyed inorganic anthropogenic waste.2009-0009-DWQ 7 September 02, 2009

OrderG. Determining and Reducing Risk46. The risk of accelerated erosion and sedimentation from wind and waterdepends on a number of factors, including proximity to receiving waterbodies, climate, topography, and soil type.47. This General Permit requires dischargers to assess the risk level of asite based on both sediment transport and receiving water risk. ThisGeneral Permit contains requirements for Risk Levels 1, 2 and 3, andLUP Risk Type 1, 2, and 3 (Attachment A). Risk levels are establishedby determining two factors: first, calculating the site's sediment risk;and second, receiving water risk during periods of soil exposure (i.e.grading and site stabilization). Both factors are used to determine thesite-specific Risk Level(s). LUPs can be determined to be Type 1based on the flowchart in Attachment A.1.48. Although this General Permit does not mandate specific setbackdistances, dischargers are encouraged to set back their constructionactivities from streams and wetlands whenever feasible to reduce therisk of impacting water quality (e.g., natural stream stability and habitatfunction). Because there is a reduced risk to receiving waters whensetbacks are used, this General Permit gives credit to setbacks in therisk determination and post-construction storm water performancestandards. The risk calculation and runoff reduction mechanisms inthis General Permit are expected to facilitate compliance with anyRegional Water Board and local agency setback requirements, and toencourage voluntary setbacks wherever practicable.49. Rain events can occur at any time of the year in California. Therefore,a Rain Event Action Plan (REAP) is necessary for Risk Level 2 and 3traditional construction projects (LUPs exempt) to ensure that activeconstruction sites have adequate erosion and sediment controlsimplemented prior to the onset of a storm event, even if construction isplanned only during the dry season.50. Soil particles smaller than 0.02 millimeters (mm) (i.e., finer thanmedium silt) do not settle easily using conventional measures forsediment control (i.e., sediment basins). Given their long settling time,dislodging these soils results in a significant risk that fine particles willbe released into surface waters and cause unacceptable downstreamimpacts. If operated correctly, an Active Treatment System (ATS 5 ) canprevent or reduce the release of fine particles from construction sites.5 An ATS is a treatment system that employs chemical coagulation, chemical flocculation, or electrocoagulation in order to reduce turbidity caused by fine suspended sediment.2009-0009-DWQ 8 September 02, 2009

OrderUse of an ATS can effectively reduce a site's risk of impactingreceiving waters.51. Dischargers located in a watershed area where a Total Maximum DailyLoad (TMDL) has been adopted or approved by the Regional WaterBoard or U.S. EPA may be required by a separate Regional WaterBoard action to implement additional BMPs, conduct additionalmonitoring activities, and/or comply with an applicable waste loadallocation and implementation schedule. Such dischargers may alsobe required to obtain an individual Regional Water Board permitspecific to the area.H. Effluent Standards52. The State Water Board convened a blue ribbon panel of storm waterexperts that submitted a report entitled, “The Feasibility of NumericEffluent Limits Applicable to Discharges of Storm Water Associatedwith Municipal, Industrial and Construction Activities,” datedJune 19, 2006. The panel concluded that numeric limits or actionlevels are technically feasible to control construction storm waterdischarges, provided that certain conditions are considered. The panelalso concluded that numeric effluent limitations (NELs) are feasible fordischarges from construction sites that utilize an ATS. The StateWater Board has incorporated the expert panel’s suggestions into thisGeneral Permit, which includes both numeric action levels (NALs) andNELs for pH and turbidity, and special numeric limits for ATSdischarges.Numeric Effluent Limitations53. Discharges of storm water from construction activities may becomecontaminated from alkaline construction materials resulting in high pH(greater than pH 7). Alkaline construction materials include, but arenot limited to, hydrated lime, concrete, mortar, cement kiln dust (CKD),Portland cement treated base (CTB), fly ash, recycled concrete, andmasonry work. This General Permit includes an NEL for pH (6.0-9.0)that applies only at sites that exhibit a "high risk of high pH discharge."A "high risk of high pH discharge" can occur during the completeutilities phase, the complete vertical build phase, and any portion ofany phase where significant amounts of materials are placed directlyon the land at the site in a manner that could result in significantalterations to the background pH of any discharges.54. For Risk Level 3 discharges, this General Permit establishestechnology-based, numeric effluent limitations (NELs) for turbidity of500 NTU. Exceedances of the turbidity NEL constitutes a violation ofthis General Permit.2009-0009-DWQ 9 September 02, 2009

Order55. This General Permit establishes a 5 year, 24 hour (expressed in inchesof rainfall) Compliance Storm Event exemption from the technologybasedNELs for Risk Level 3 dischargers.Determining Compliance with Numeric Limitations56. This General Permit sets a pH NAL of 6.5 to 8.5, and a turbidity NAL of250 NTU. The purpose of the NAL and its associated monitoringrequirement is to provide operational information regarding theperformance of the measures used at the site to minimize thedischarge of pollutants and to protect beneficial uses and receivingwaters from the adverse effects of construction-related storm waterdischarges. The NALs in this General Permit for pH and turbidity arenot directly enforceable and do not constitute NELs.57. This General Permit requires dischargers with NAL exceedances toimmediately implement additional BMPs and revise their Storm WaterPollution Prevention Plans (SWPPPs) accordingly to either preventpollutants and authorized non-storm water discharges fromcontaminating storm water, or to substantially reduce the pollutants tolevels consistently below the NALs. NAL exceedances are reported inthe State Water Boards SMARTS system, and the discharger isrequired to provide an NAL Exceedance Report when requested by aRegional Water Board.58. If run-on is caused by a forest fire or any other natural disaster, thenNELs do not apply.59. Exceedances of the NELs are a violation of this Permit. This GeneralPermit requires dischargers with NEL exceedances to implementadditional monitoring, BMPs, and revise their SWPPPs accordingly.Dischargers are required to notify the State and Regional WaterBoards of the violation through the State Water Boards SMARTssystem, and provide an NEL Violation Report sharing additionalinformation concerning the NEL exceedance.I. Receiving Water Limitations60. This General Permit requires all enrolled dischargers to determine thereceiving waters potentially affected by their discharges and to complywith all applicable water quality standards, including any more stringentstandards applicable to a water body.J. Sampling, Monitoring, Reporting and Record Keeping61. Visual monitoring of storm water and non-storm water discharges isrequired for all sites subject to this General Permit.2009-0009-DWQ 10 September 02, 2009

Order62. Records of all visual monitoring inspections are required to remain onsiteduring the construction period and for a minimum of three years.63. For all Risk Level 3 and Risk Level 2 sites, this General Permitrequires effluent monitoring for pH and turbidity. Sampling, analysisand monitoring requirements for effluent monitoring for pH and turbidityare contained in this General Permit.64. Risk Level 3 sites in violation of the Numeric Effluent Limitationscontained in this General Permit and with direct discharges to receivingwater are required to conduct receiving water monitoring.65. For Risk Level 3 sites larger than 30 acres and with direct dischargesto receiving waters, this General Permit requires bioassessmentsampling before and after site completion to determine if significantdegradation to the receiving water’s biota has occurred.Bioassessment sampling guidelines are contained in this GeneralPermit.66. A summary and evaluation of the sampling and analysis results will besubmitted in the Annual Reports.67. This General Permit contains sampling, analysis and monitoringrequirements for non-visible pollutants at all sites subject to thisGeneral Permit.68. Compliance with the General Permit relies upon dischargers toelectronically self-report any discharge violations and to comply withany Regional Water Board enforcement actions.69. This General Permit requires that all dischargers maintain a paper orelectronic copy of all required records for three years from the dategenerated or date submitted, whichever is last. These records must beavailable at the construction site until construction is completed. ForLUPs, these documents may be retained in a crew member’s vehicleand made available upon request.K. Active Treatment System (ATS) Requirements70. Active treatment systems add chemicals to facilitate flocculation,coagulation and filtration of suspended sediment particles. Theuncontrolled release of these chemicals to the environment cannegatively affect the beneficial uses of receiving waters and/or degradewater quality (e.g., acute and chronic toxicity). Additionally, the batchstorage and treatment of storm water through an ATS' can potentially2009-0009-DWQ 11 September 02, 2009

Ordercause physical impacts on receiving waters if storage volume isinadequate or due to sudden releases of the ATS batches andimproperly designed outfalls.71. If designed, operated and maintained properly an ATS can achievevery high removal rates of suspended sediment (measured asturbidity), albeit at sometimes significantly higher costs than traditionalerosion/sediment control practices. As a result, this General Permitestablishes NELs consistent with the expected level of typical ATSperformance.72. This General Permit requires discharges of storm water associatedwith construction activity that undergo active treatment to comply withspecial operational and effluent limitations to ensure that thesedischarges do not adversely affect the beneficial uses of the receivingwaters or cause degradation of their water quality.73. For ATS discharges, this General Permit establishes technology-basedNELs for turbidity.74. This General Permit establishes a 10 year, 24 hour (expressed ininches of rainfall) Compliance Storm Event exemption from thetechnology-based numeric effluent limitations for ATS discharges.Exceedances of the ATS turbidity NEL constitutes a violation of thisGeneral Permit.L. Post-Construction Requirements75. This General Permit includes performance standards for postconstructionthat are consistent with State Water Board Resolution No.2005-0006, "Resolution Adopting the Concept of Sustainability as aCore Value for State Water Board Programs and Directing ItsIncorporation," and 2008-0030, “Requiring Sustainable WaterResources Management.“ The requirement for all construction sites tomatch pre-project hydrology will help ensure that the physical andbiological integrity of aquatic ecosystems are sustained. This “runoffreduction” approach is analogous in principle to Low ImpactDevelopment (LID) and will serve to protect related watersheds andwaterbodies from both hydrologic-based and pollution impactsassociated with the post-construction landscape.76. LUP projects are not subject to post-construction requirements due tothe nature of their construction to return project sites to preconstructionconditions.2009-0009-DWQ 12 September 02, 2009

OrderM. Storm Water Pollution Prevention Plan Requirements77. This General Permit requires the development of a site-specificSWPPP. The SWPPP must include the information needed todemonstrate compliance with all requirements of this General Permit,and must be kept on the construction site and be available for review.The discharger shall ensure that a QSD develops the SWPPP.78. To ensure proper site oversight, this General Permit requires aQualified SWPPP Practitioner to oversee implementation of the BMPsrequired to comply with this General Permit.N. Regional Water Board Authorities79. Regional Water Boards are responsible for implementation andenforcement of this General Permit. A general approach to permittingis not always suitable for every construction site and environmentalcircumstances. Therefore, this General Permit recognizes thatRegional Water Boards must have some flexibility and authority toalter, approve, exempt, or rescind permit authority granted under thisGeneral Permit in order to protect the beneficial uses of our receivingwaters and prevent degradation of water quality.2009-0009-DWQ 13 September 02, 2009

OrderIT IS HEREBY ORDERED that all dischargers subject to this General Permitshall comply with the following conditions and requirements (including allconditions and requirements as set forth in Attachments A, B, C, D, E and F) 6 :II. CONDITIONS FOR PERMIT COVERAGEA. Linear Underground/Overhead Projects (LUPs)1.

Only LUPs shall comply with the conditions and requirements inAttachment A, A.1 & A.2 of this Order. The balance of this Order is notapplicable to LUPs except as indicated in Attachment A.B. Obtaining Permit Coverage Traditional Construction Sites6 These attachments are part of the General Permit itself and are not separate documents that are capableof being updated independently by the State Water Board.2009-0009-DWQ 14 September 02, 2009

Order1. The Legally Responsible Person (LRP) (see Special Provisions,Electronic Signature and Certification Requirements, Section IV.I.1)must obtain coverage under this General Permit.2. To obtain coverage, the LRP must electronically file PermitRegistration Documents (PRDs) prior to the commencement ofconstruction activity. Failure to obtain coverage under this GeneralPermit for storm water discharges to waters of the United States is aviolation of the CWA and the California Water Code.3. PRDs shall consist of:a. Notice of Intent (NOI)b. Risk Assessment (Section VIII)c. Site Mapd. Storm Water Pollution Prevention Plan (Section XIV)e. Annual Feef. Signed Certification StatementAny information provided to the Regional Water Board shall complywith the Homeland Security Act and any other federal law thatconcerns security in the United States; any information that does notcomply should not be submitted.Attachment B contains additional PRD information. Dischargers mustelectronically file the PRDs, and mail the appropriate annual fee to theState Water Board.4. This permit is effective on July 1, 2010.a. Dischargers Obtaining Coverage On or After July 1, 2010: Alldischargers requiring coverage on or after July 1, 2010, shallelectronically file their PRDs prior to the commencement ofconstruction activities, and mail the appropriate annual fee no laterthan seven days prior to the commencement of constructionactivities. Permit coverage shall not commence until the PRDs andthe annual fee are received by the State Water Board, and a WDIDnumber is assigned and sent by SMARTS.b. Dischargers Covered Under 99-08-DWQ and 2003-0007-DWQ:Existing dischargers subject to State Water Board Order No. 99-08-DWQ (existing dischargers) will continue coverage under 99-08-DWQ until July 1, 2010. After July 1, 2010, all NOIs subject toState Water Board Order No. 99-08-DWQ will be terminated.Existing dischargers shall electronically file their PRDs no later than2009-0009-DWQ 15 September 02, 2009

OrderJuly 1, 2010. If an existing discharger’s site acreage subject to theannual fee has changed, it shall mail a revised annual fee no lessthan seven days after receiving the revised annual fee notification,or else lose permit coverage. All existing dischargers shall beexempt from the risk determination requirements in Section VIII ofthis General Permit until two years after permit adoption. Allexisting dischargers are therefore subject to Risk Level 1requirements regardless of their site’s sediment and receiving waterrisks. However, a Regional Board retains the authority to requirean existing discharger to comply with the Section VIII riskdetermination requirements.5. The discharger is only considered covered by this General Permit uponreceipt of a Waste Discharger Identification (WDID) number assignedand sent by the State Water Board Storm water Multi-Application andReport Tracking System (SMARTS). In order to demonstratecompliance with this General Permit, the discharger must obtain aWDID number and must present documentation of a valid WDID upondemand.6. During the period this permit is subject to review by the U.S. EPA, theprior permit (State Water Board Order No. 99-08-DWQ) remains ineffect. Existing dischargers under the prior permit will continue to havecoverage under State Water Board Order No. 99-08-DWQ until thisGeneral Permit takes effect on July 1, 2010. Dischargers whocomplete their projects and electronically file an NOT prior to July 1,2010, are not required to obtain coverage under this General Permit.7. Small Construction Rainfall Erosivity WaiverEPA’s Small Construction Erosivity Waiver applies to sites betweenone and five acres demonstrating that there are no adverse waterquality impacts.Dischargers eligible for a Rainfall Erosivity Waiver based on lowerosivity potential shall complete the electronic Notice of Intent (NOI)and Sediment Risk form through the State Water Board’s SMARTSsystem, certifying that the construction activity will take place during aperiod when the value of the rainfall erosivity factor is less than five.Where the LRP changes or another LRP is added during construction,the new LRP must also submit a waiver certification through theSMARTS system.If a small construction site continues beyond the projected completiondate given on the waiver certification, the LRP shall recalculate therainfall erosivity factor for the new project duration and submit this2009-0009-DWQ 16 September 02, 2009

Orderinformation through the SMARTS system. If the new R factor is belowfive (5), the discharger shall update through SMARTS all applicableinformation on the waiver certification and retain a copy of the revisedwaiver onsite. The LRP shall submit the new waiver certification 30days prior to the projected completion date listed on the original waiverform to assure exemption from permitting requirements isuninterrupted. If the new R factor is five (5) or above, the LRP shall berequired to apply for coverage under this Order.8. In the case of a public emergency that requires immediate constructionactivities, a discharger shall submit a brief description of theemergency construction activity within five days of the onset ofconstruction, and then shall submit all PRDs within thirty days.C. Revising Permit Coverage for Change of Acreage or New Ownership1. The discharger may reduce or increase the total acreage coveredunder this General Permit when a portion of the site is complete and/orconditions for termination of coverage have been met (See Section II.DConditions for Termination of Coverage); when ownership of a portionof the site is sold to a different entity; or when new acreage, subject tothis General Permit, is added to the site.2. Within 30 days of a reduction or increase in total disturbed acreage,the discharger shall electronically file revisions to the PRDs thatinclude:a. A revised NOI indicating the new project size;b. A revised site map showing the acreage of the site completed,acreage currently under construction, acreage sold/transferred oradded, and acreage currently stabilized in accordance with theConditions for Termination of Coverage in Section II.D below.c. SWPPP revisions, as appropriate; andd. Certification that any new landowners have been notified ofapplicable requirements to obtain General Permit coverage. Thecertification shall include the name, address, telephone number,and e-mail address of the new landowner.e. If the project acreage has increased, dischargers shall mailpayment of revised annual fees within 14 days of receiving therevised annual fee notification.2009-0009-DWQ 17 September 02, 2009

Order3. The discharger shall continue coverage under the General Permit forany parcel that has not achieved “Final Stabilization” as defined inSection II.D.4. When an LRP owns property with active General Permit coverage, andthe LRP sells the property, or a parcel thereof, to another person, thatperson shall become an LRP with respect to whatever parcel was sold.The existing LRP shall inform the new LRP of the General Permit’srequirements. In order for the new LRP to continue the constructionactivity on its parcel of property, the new LRP, or the new LRP’sapproved signatory, must submit PRDs in accordance with thisGeneral Permit’s requirements.D. Conditions for Termination of Coverage1. Within 90 days of when construction is complete or ownership hasbeen transferred, the discharger shall electronically file a Notice ofTermination (NOT), a final site map, and photos through the StateWater Boards SMARTS system. Filing a NOT certifies that all GeneralPermit requirements have been met. The Regional Water Board willconsider a construction site complete only when all portions of the sitehave been transferred to a new owner, or all of the following conditionshave been met:a. For purposes of “final stabilization,” the site will not pose anyadditional sediment discharge risk than it did prior to thecommencement of construction activity;b. There is no potential for construction-related storm water pollutantsto be discharged into site runoff;c. Final stabilization has been reached;d. Construction materials and wastes have been disposed of properly;e. Compliance with the Post-Construction Standards in Section XIII ofthis General Permit has been demonstrated;f. Post-construction storm water management measures have beeninstalled and a long-term maintenance plan 7 has been established;and7 For the purposes of this requirement a long-term maintenance plan will be designed for a minimum of fiveyears, and will describe the procedures to ensure that the post-construction storm water managementmeasures are adequately maintained.2009-0009-DWQ 18 September 02, 2009

Orderg. All construction-related equipment, materials and any temporaryBMPs no longer needed are removed from the site.2. The discharger shall certify that final stabilization conditions aresatisfied in their NOT. Failure to certify shall result in continuation ofpermit coverage and annual billing.3. The NOT must demonstrate through photos, RUSLE or RUSLE2, orresults of testing and analysis that the site meets all of the conditionsabove (Section II.D.1) and the final stabilization condition (SectionII.D.1.a) is attained by one of the following methods:a. “70% final cover method,” no computational proof requiredOR:b. “RUSLE or RUSLE2 method,” computational proof requiredOR:c. “Custom method”, the discharger shall demonstrate in some othermanner than a or b, above, that the site complies with the “finalstabilization” requirement in Section II.D.1.a.2009-0009-DWQ 19 September 02, 2009

For sites whose disturbed area exceeds two acres, the discharger shallpreserve the pre-construction drainage density (miles of stream lengthper square mile of drainage area) for all drainage areas within the areaserving a first order stream 14 or larger stream and ensure that postprojecttime of runoff concentration is equal or greater than pre-projecttime of concentration.14 A first order stream is defined as a stream with no tributaries.2009-0009-DWQ 36 September 02, 2009

OrderB. All dischargers shall implement BMPs to reduce pollutants in storm waterdischarges that are reasonably foreseeable after all construction phaseshave been completed at the site (Post-construction BMPs).2009-0009-DWQ 37 September 02, 2009

OrderXIV. SWPPP REQUIREMENTSA. The discharger shall ensure that the Storm Water Pollution PreventionPlans (SWPPPs) for all traditional project sites are developed andamended or revised by a QSD. The SWPPP shall be designed to addressthe following objectives:1. All pollutants and their sources, including sources of sedimentassociated with construction, construction site erosion and all otheractivities associated with construction activity are controlled;2. Where not otherwise required to be under a Regional Water Boardpermit, all non-storm water discharges are identified and eithereliminated, controlled, or treated;3. Site BMPs are effective and result in the reduction or elimination ofpollutants in storm water discharges and authorized non-storm waterdischarges from construction activity to the BAT/BCT standard;4. Calculations and design details as well as BMP controls for site run-onare complete and correct, and5. Stabilization BMPs installed to reduce or eliminate pollutants afterconstruction are completed.B. To demonstrate compliance with requirements of this General Permit, theQSD shall include information in the SWPPP that supports theconclusions, selections, use, and maintenance of BMPs.C. The discharger shall make the SWPPP available at the construction siteduring working hours while construction is occurring and shall be madeavailable upon request by a State or Municipal inspector. When theoriginal SWPPP is retained by a crewmember in a construction vehicleand is not currently at the construction site, current copies of the BMPsand map/drawing will be left with the field crew and the original SWPPPshall be made available via a request by radio/telephone.2009-0009-DWQ 38 September 02, 2009

OrderXV. REGIONAL WATER BOARD AUTHORITIESA. In the case where the Regional Water Board does not agree with thedischarger’s self-reported risk level (e.g., they determine themselves to bea Level 1 Risk when they are actually a Level 2 Risk site), Regional WaterBoards may either direct the discharger to reevaluate the Risk Level(s) fortheir site or terminate coverage under this General Permit.B. Regional Water Boards may terminate coverage under this GeneralPermit for dischargers who fail to comply with its requirements or wherethey determine that an individual NPDES permit is appropriate.C. Regional Water Boards may require dischargers to submit a Report ofWaste Discharge / NPDES permit application for Regional Water Boardconsideration of individual requirements.D. Regional Water Boards may require additional Monitoring and ReportingProgram Requirements, including sampling and analysis of discharges tosediment-impaired water bodies.E. Regional Water Boards may require dischargers to retain records for morethan the three years required by this General Permit.2009-0009-DWQ 39 September 02, 2009

OrderXVI. ANNUAL REPORTING REQUIREMENTSA. All dischargers shall prepare and electronically submit an Annual Reportno later than September 1 of each year.B. The discharger shall certify each Annual Report in accordance with theSpecial Provisions.C. The discharger shall retain an electronic or paper copy of each AnnualReport for a minimum of three years after the date the annual report isfiled.D. The discharger shall include storm water monitoring information in theAnnual Report consisting of:1. a summary and evaluation of all sampling and analysis results,including copies of laboratory reports;2. the analytical method(s), method reporting unit(s), and methoddetection limit(s) of each analytical parameter (analytical results thatare less than the method detection limit shall be reported as "less thanthe method detection limit");3. a summary of all corrective actions taken during the compliance year;4. identification of any compliance activities or corrective actions thatwere not implemented;5. a summary of all violations of the General Permit;6. the names of individual(s) who performed the facility inspections,sampling, visual observation (inspections), and/or measurements;7. the date, place, time of facility inspections, sampling, visualobservation (inspections), and/or measurements, includingprecipitation (rain gauge); and8. the visual observation and sample collection exception records andreports specified in Attachments C, D, and E.E. The discharger shall provide training information in the Annual Reportconsisting of:1. documentation of all training for individuals responsible for all activitiesassociated with compliance with this General Permit;2009-0009-DWQ 40 September 02, 2009

Order2. documentation of all training for individuals responsible for BMPinstallation, inspection, maintenance, and repair; and3. documentation of all training for individuals responsible for overseeing,revising, and amending the SWPPP.2009-0009-DWQ 41 September 02, 2009
