six required elements that, when implemented together, are expected to reduce pollutants discharged into receiving water bodies to the maximum extent practicable (MEP). The new permit revises, and to some extent, reorganizes the existing Minimum Control Measures (MCMs), to include additional controls and details where appropriate. This revised list of six program elements, or MCMs, includes: 1) Public Education, Outreach, and Involvement; 2) Illicit Discharge Detection and Elimination; 3) Construction Site Stormwater Runoff Control; 4) Post-Construction Stormwater Management in New Development and Redevelopment; 5) Pollution Prevention and Good Housekeeping for Municipal Operations; and 6) Industrial Stormwater Sources. MCM (6) is required only for Level 4 MS4s, as they are similar in populations to Phase I MS4s, which this MCM is based on. The permit maintains the optional 7 th MCM, related to construction activities where the small MS4 is the site operator (reference Permit Part III.B). The implementation and evaluation of these MCMs comprise the heart of the City's SWMP. Included within each MCM category is information about: · Best Management Practices (BMPs) that will be implemented, as appropriate; · The clear, specific and measurable goals for each of the BMPs, including, as appropriate the months and years in which the applicant will take the required actions, including interim milestones and the frequency of the action; and · The person or persons responsible for implementing or coordinating the applicants SWMP. This revised stormwater management plan was submitted to TCEQ in July 2019 with a notice of intent (NOI) to the TCEQ to meet the requirements of the new permit. Any BMPs that were found not to be effective in the previous permit can be modified or removed with justification. The City received comments on the revised stormwater management plan on January 4, 2021. This 2021 revision addresses these comments from TCEQ. The City will continue to implement this SWMP while waiting on TCEQ approval. B. SWMP DEVELOPMENT This document is a revised version of the 2014 Stormwater Management Plan originally prepared by Paredes-Garcia & Associates (PGA). A BMP review was performed to determine the effectiveness and appropriateness of each BMP, and to ensure that resources and funding can be met. City staff was asked to review the list and indicate which BMPs are already implemented or can be implemented in the new permit. Also, city staff identified potential changes to BMPs that were found to be ineffective or inappropriate due to lack of participation, funding constraints, and/or not required of Level 2 MS4s. BMPs were also modified based on the new general permit requirements. Suggested changes were reviewed and compared with regulatory requirements in the permit for each MCM. The revised list of BMPs to reduce pollutants to the maximum extent practicable is included in this SWMP document. The draft revised SWMP and NOI will be submitted to TCEQ within the allowed 180-day period for application of coverage, as specified in the permit. Authorization will begin when the City is notified that the TCEQ has approved the NOI and SWMP, and after the City has met the Public Notice process described below. This SWMP and its included BMPs will be reviewed and updated annually by the permittee as necessary. C. PUBLIC PARTICIPATION As an applicant under the TCEQ general MS4 permit, the City must comply with the following public 1/2021 Stormwater ManagementPlan 2
notice procedures: i. The applicant must submit the NOI and a SWMP to the TCEQ executive director. ii. After the applicant receives written instructions from the TCEQ’s Office of Chief Clerk, the applicant must publish notice of the executive director’s preliminary decision on the NOI and SWMP. iii. The notice will include the following information, at a minimum: a. The legal name of the MS4 operator; b. Indication of whether the NOI is for a new authorization or is a renewal of an existing authorization; c. The address of the applicant; d. A brief summary of the information included in the NOI, such as the general location of the small MS4 and a description of the classified receiving waters that receive the discharges from the small MS4; e. The location and mailing address where the public may provide comments to the TCEQ; f. The public location where copies of the NOI and SWMP, as well as the executive director's general permit and fact sheet, may be reviewed; and g. If required by the executive director, the date, time, and location of the public meeting. iv. This notice must be published at least once in a newspaper of general circulation in the municipality or county where the small MS4 is located. If the small MS4 is located in multiple municipalities or counties, the notice must be published at least once in a newspaper of general circulation in the municipality or county containing the largest resident population for the regulated portion of the small MS4. This notice must provide opportunity for the public to submit comments on the NOI and SWMP. In addition, the notice must allow the public to request a public meeting. A public meeting (equivalent to a “public hearing” as required by 40 CFR §122.28(d)(2)(ii)) will be held if the TCEQ determines that there is significant public interest. v. The public comment period begins on the first date the notice is published and lasts for at least 30 days. If a public meeting is held, the comment period will end at the closing of the public meeting (see paragraph (f) below). The public may submit written comments to the TCEQ Office of Chief Clerk during the comment period detailing how the NOI or SWMP for the small MS4 fails to meet the technical requirements or conditions of this general permit. vi. If significant public interest exists, the executive director will direct the applicant to publish a notice of the public meeting and to hold the public meeting. The applicant shall publish notice of a public meeting at least 30 days before the meeting and hold the public meeting in a county where the small MS4 is located. TCEQ staff will facilitate the meeting. vii. If a public meeting is held, the applicant shall describe the contents of the NOI and SWMP. The applicant shall also provide maps and other data on the small MS4. The applicant shall provide a sign in sheet for attendees to register their names and addresses and furnish the sheet to the executive director. A public meeting held under this general permit is not an evidentiary proceeding. viii. The applicant shall file with the Chief Clerk a copy and an affidavit of the publication of notice(s) within 60 days of receiving the written instructions from the Chief Clerk. ix. The executive director, after considering public comment, will either approve, approve with conditions, or deny the NOI based on whether the NOI and SWMP meet the requirements of this general permit. x. Persons whose names and addresses appear legibly on the sign-in sheet from the public meeting and persons who submitted written comments to the TCEQ will be notified by the TCEQ’s Office of Chief Clerk of the executive director’s decision regarding the authorization. 1/2021 Stormwater ManagementPlan 3
