Regulations/Activity Prior to January 31, 2012• Land Development Code– Prior to 1990, El Paso County considered oil and gas operations as Mineral ResourcesExtraction, regulated via Special Use permit (BOCC hearing).– 1990 Land Development Code Amendments clarified the definition of mineral and mineralresources extraction to effectively exclude oil and gas drilling from the definition of mineralresources extraction, without adding any specific new provisions addressing oil and gasoperations.– As a result of the amendments, the Code did not address specific zoning or developmentstandards for oil and gas operations (exploration or production).– Therefore, the Temporary Use Permit process was used to process applications for exploratorywells.• Development Activity– ETOCOReceived approval of two (2) temporary use applications for exploratory drilling(State and Ververs wells). Only the Ververs well was drilled.and testing– Pine Ridge Oil and Gas, LLCReceived approval of three (3) temporary use applications for exploratory drilling and testing(Naos, Vela, and Carina wells). Only the Naos well was drilled.– Ultra Resources, Inc.Received approval of three (3) temporary use applications for exploratory drilling and testing(Olive Oyl, Brutus, and Spinach wells). To date, the Olive Oyl well has been drilled andthe Brutus well pad earthwork is under construction.
Regulations/Activity Since January 31, 2012• Land Development Code– January 31, 2012 - Board of County Commissioners Adopted Section 5.2.37 Oiland/or Gas Operations as an amendment to the Land Development Code, whichincluded specific regulations pertaining to:• Transportation,• Groundwater Quality Monitoring,• Noxious Weed Management, and• Emergency Response Planning.– As a result of the amendments, all oil and/or gas operations are processed asspecial uses, which may be approved administratively by the DSD Director.• Development Activity– Ultra Resources, Inc.Submitted two (2) special use applications to expand the drilling operations ontwo sites (Olive Oyl and Brutus well sites) to allow up to eight (8) horizontal wells.Also, submitted one (1) special use application for a new drilling site, Ponderosa,which is proposed to include a single vertical well and up to four (4) horizontalwells.– Hilcorp Energy CompanySubmitted two (2) Early Assistance Meeting Applications for drilling operations ontwo sites (see next slide).
Areas of Planning Review• Emergency Response Plan– Referred to the County Office of Emergency Management via referralfrom DSD for review.• Noxious Weed Management Plan– Referred to EPC Environmental Services and the Natural ResourcesConservation Service (NRCS) for review.• Groundwater Monitoring Plan– Either the COGA voluntary program or EPC testing program in 5.2.37.– Referred to and data maintained by COGCC and EPC Health.

Areas of Engineering Review• Erosion & Stormwater Control• Transportation Impacts
Engineering Review - Erosion & Stormwater• Erosion & Stormwater Quality Control Plan (ESQCP)– Required by Colorado Department of Public Health andEnvironment (CDPHE) who have directed us to continue to require it.• Financial Assurances• Stormwater Management Plan• Grading & Erosion Control Plan (ESQCP is nexus)
Engineering Review – Transportation Impacts• Development Services Department (DSD) Review– Transportation Impact Study, including:• Traffic volumes• Public improvements, if triggered• Haul route plan• Construction drawings for any necessary public improvements• May require applicant to provide maintenance during project• Public Services Department (PSD) Review (concurrent process)– Designates County-wide haul routes– Reviews and issues the following permits:• Temporary access permit (routed through DSD, approved by PSD)– Determines bond amount• Issues “Work-in-ROW” permit– Temporary traffic control (MHT)– Specifies detour plans, if any
