Facili R resentative s /Title s :John Hue ecto s : Kath Rosow CDPHE CD Inspection Findings Records Review Note: The permit certification effective date was Mazch 1, 2004. The date that land-disturbing activities began at the site was approximately September 2004, as provided by Ms. DeVincentis, Head of Permits (Western Gravel, Inc.). Certification No. COG-500451 covers both process water and Stormwater dischazges associated with sand and gravel operations at this location. Compliance with the Stormwater requirements of the permit, only, was evaluated during the inspection of this facility. 1. A copy of the Stormwater Management Plan (SWMP) was retained onsite. The SWMP was reviewed and found to be inadequate for the reasons listed below. A copy of the updated SWMP must be submitted to the Division. a. The Site Map did not indicate all items required by the permit, and did not reflect current site conditions. For example, the Site Map did not provide an outline of the Stormwater drainage area; the estimate o£the direction of flow; existing structural control measures to reduce pollutants in Stormwater runoff; and the boundary of tributary area that is subject to effluent limitations. hr addition, the Site Map indicated many hears that were not verified duning the field inspection (i.e., sediment pond; staging azea; access roads; portable asphalt plant, etc). The Site Map must be updated to indicate all items required by the permit, and must reflect current site conditions. b. The section in the SWMP on Description of Potential Pollutant Sorsces/Material Inventory did not identify all potential pollutant sources at the site, and did not reflect current site conditions. For example, stockpiled material was not identified as a potenfia] pollutant source in this section of the SWMP, whereas, gasoline and AC-10 hot asphalt material were identified as potential pollutant sources, but will not be used on-site. The SWMP must be updated to identify all potential pollutant sources on site, and must reflect current site conditions. c. The section in the S WMP on Stormwater Quality Controls did not describe BMPs to be used to reduce erosion and prevent sediment dischazge from soil berms located at the southwest and eastern perimeters of the site. The ~ SWMP must be updated to include this information. 2. Comprehensive inspection records were not available for review at the 6me of the inspection. If comprehensive inspections have been conducted, a copy of the inspection records for the past two years must be submitted to the Division. If comprehensive inspections have not been conducted, a written explanation of this fact must be submitted to the Division, including a description of what steps will be taken to ensure that inspections aze conducted in the future.
