HomeMy WebLinkAbout1.08 Section 7-102Sourceas Article VII, §7 -102 Compliance with Comprehensive Plan and Intergovernmental Agreements: The proposed Spring Valley Compressor Station (SVCS) would be in compliance with the Garfield County Comprehensive Plan (2030; adopted 11/10/2010) — referred to hence forward as CP 2030, and is situated in Comprehensive Plan Study Area 2. The proposed project has taken in consideration all plan elements listed in Chapter 3. This project will be managed throughout its life according to the policies listed in Section 9, Mineral Extraction, of the Garfield County Comprehensive Plan 2030. Facilities that are appurtenances to oil/ gas development activities (compressors, etc.) are considered appropriate in all land uses so long as they meet the respective mitigation requirements of the ULUR to maintain compatibility with surrounding land uses./ Such steps to ensure compliance include the following permits and documents: • Limited Impact Review o Impact Analysis o Noise Study o Geology Report o Biological Report o Noxious Weed Management Plan o Traffic Analysis o Cultural Resource Analysis o Spill Prevention Control and Countermeasure Plan o Stormwater Management Plan o Emergency Response Plan o Soils Report o Reclamation Plan o Landscape Plan • Air Permits • Location and Extent Permit Section 1: Urban Growth Areas & Intergovernmental Coordination — CP 2030 The compressor station is located on J & S Nieslanik LLLP property. The property is currently zoned as Rural. The compressor station, situated in the NWNE of Section 3, Township 7 South, Range 88 West of the sixth (6th) Principal Meridian (P.M.), falls outside of the locally planned Urban Growth Area. There are no intergovernmental agreements between the County and the Nieslanik family in the area where the compressor station will be constructed and operated. Please refer to Attachment 1 for supporting documentation. 'Garfield County Comprehensive Plan (2030; adopted 11/10/2010); Section 9 Mineral Extraction, Policy: 4, pg. 61 SVCS — Location & Extent 1 Sourceas Section 2: Housing — CP 2030 Section 2 is not applicable to scope of this project. Section 3: Transportation — CP 2030 The proposed road associated with the compressor station runs through the Nieslanik family's private property and connects with an existing two - track. The improved upon existing two -track also runs through the Nieslanik property, Both the existing and proposed roads would provide a road system for the associated traffic with regards to safety, separation from living areas, convenience and access. The access road would provide adequate access for police and fire protection. A basic traffic assessment was completed. Based on this assessment, the traffic increase associated with the SVCS is considered minimal. In the event dust suppression is required due to an increased traffic load associated with the SVCS, Rocky Mountain Natural Gas (RMNG) would dispatch water trucks to applicable stretches of roadway. When applicable, RMNG would provide signage to ensure the respective roadways are appropriately marked for commercial and residential traffic. To view the complete assessment, refer to section II.e of the SVCS Limited Impact Review. Section 4: Economics, Employment and Tourism — CP 2030 The development of the SVCS would not have an adverse impact on the surrounding area and is compatible with the scale, intensity and type of uses located on adjacent property. Please see section I.b.8 for a map of the surrounding land uses. The development of the SVCS shall not reduce views and is not located in an area that would have an adverse effect on the tourism industry of the respective region. The respective construction will be visible from CR 115, visual effects will be mitigated using design techniques compatible with the surrounding natural environment, refer to the viewshed analysis in tab II.p of the Limited Impact Review application package. It should be noted that the proposed compressor would be painted regulated muted colors in accordance with the surrounding landscape's vegetation any typical BLM recommendations for the surrounding landscape. It should be noted that the proposed compressor station would have a positive effect on the region with regards to job security and creation especially during the construction phase of the proposed project. The compressor station will allow RMNG to ensure that gas will be supplied during peak season to residential, private and commercial industrial customers not just in Garfield County, but all of the counties upstream and downstream of the facility RMNG is servicing. Section 5: Recreation, Open Space, and Trails — CP 2030 With regards to recreation and trails, this section is not applicable to the scope of this project. Section 6: Agriculture — CP 2030 The proposed project would not adversely impact agricultural operations on or adjacent to the project site. The property owner's hay farm is Iocated directly adjacent to the compressor SVCS — Location & Extent 2 Sourceas easement and there is potential that rangeland/grazing could occur on the property and in the area east of the easement since this land is managed by the BLM. Adjacent property owners will be notified of hearings through various public notices, i.e. certified mail and newspaper, at least seven (7) no more than thirty (30) days prior to date of hearings. Section 7: Water and Sewer Services — CP 2030 The compressor station would not require more water demand than the eight (8) single - family equivalents; the associated requirements of the section are currently non - applicable. Personnel onsite will only be there for routine maintenance. The office will b unmanned. SourceGas /Rocky Mountain Natural Gas LLC provide their emp oT yetis with a comfo table ai convenient place to use restroom facilities as opposed to a portable toilet. No one will be staying on location for a great length of time. Additionally the water system is now NON - POTABLE for use in the restroom. The water storage tank is to be installed inside the control building and will be a maximum size of 250 gallon. All drinking water will be bottled. The water would be trucked to the facility from an approved local potable water source. Please see Figure 1 for a visual illustration as well as the design basis for the septic leach field within the site plan. Per the Soil Capacity Percolation Report, II.n of the SVCS LIR, the proposed waste water system is adequate in accordance with Colorado Department of Public Health and Environment standards.

SPV -CIV -CALC -200 BY: M. Moellering REVISION: 0 DATE: 06/21/13 PAGE: 3 of 4 1.0 SCOPE The project is a new compressor station located in Garfield County, CO. The project requires a sewage leach field to dispose of wastewater from the bathroom located in the Control Building on the site. 2.0 METHODOLOGY Source Gas has provided percolation test results on the area where the leach field will be placed. The percolation tests indicated a percolation rate of 15 min /inch. The septic system is intended to dispose of wastewater associated with the restroom in the control building. The restroom will contain a water closet, sink, and 250 - gallon non- potable water tank. The tank will feed into a diaphragm pump and into a bladder tank, and then into the water closet and sink. A typical water closet and sink uses approximately 6L of water per use. Assuming a maximum of 10 uses per day, this gives a flow rate of 60L per day or 16gpd. This wastewater flow rate is far below the minimum design conditions set by Garfield County for a septic system, which are set assuming residential purposes (allowing for showers, kitchen, washing machine, etc.) so the design criteria was largely determined based on the minimum sizing requirements set by Garfield County, which are as follows: • 750 gallon septic tank capacity • 18" drainage trench width • 6' spacing between trenches or pipes • Grading as level as possible • 6" rock depth under distribution pipe • 2" rock depth above distribution pipe • 12" cover over distribution pipe • 1/8" per linear foot of slope from building to septic tank • 4" diameter of sewer pipe and distribution pipe. The Spring Valley Compressor Station will utilize a 1,000 gallon septic tank, 12" rock depth below the distribution pipes, 3" rock depth above the distribution pipes, and 3' of cover over the distribution pipes. Otherwise, all design criteria will match the minimum criteria set by Garfield County listed above. In order to maintain 30 square feet of absorption area, two distribution pipes 15' in length will be used for the leach field. This is an appropriate absorption area for the daily flow rate of wastewater effluent. ENGINEERING SERVICES, LL 0 CIVIL ENGINEERING CALCULATION CALC NO. SPV-CIV-CALC-200 BY: M. Moellering REVISION: 0 DATE: 06/21/13 PAGE: 4 of 4 3.0 CONCLUSIONS The leach field will be designed to dispose of 16gpd of wastewater effluent from the water closet and sink located in the Control Building. It will require one 1,000 gallon septic tank, 185 cubic feet of gravel (diameter ranging from %" to 21/2"), 65' of solid PVC pipe, and 30' of perforated PVC distribution pipe. See drawing number SPV 200 100 for specific design parameters and a complete bill of materials.
