Inspection Report (Fredlund Gravel Pit Project) Page 2 of 2 3. Employee training was not conducted as required in Part LC.9 of the permit. The permittee must develop and implement an employee education program, and identify periodic dates for this training. A summary of the topics to be discussed during [his training must be submitted [o the Division. Facility Insaection Note: Al] Best Management Practices (BMPs) mentioned in the below findings must be installed according to specifications and design criteria outlined in the SWMP. These specifications and design criteria must meet best engineering practice requirements. The facility inspection was conducted during a precipitation event. It was noted during the inspection that significant portions of the site were vegetated (see photograQhs 1 and 21, and that sand and gravel activities at the site were limited to two small pits (see photoeranhs 3 and 4) located in the southwestern and northeastern aspect of the site, respectively. A process water discharge was not observed during the inspection, nor did there appear to be any intent to dischazge process water at tins time. No materials or equipment were present onsite, and no mining activity was in progress at the time of the inspection. 4. It was noted during the inspection that the SWMP and Site Map did not reflect current conditions at the site. For example, the Site Map indicates a gravel pit in excess of 20 acres at the site; at the time of the inspection, however, it was noted that sand and gravel activities at the site were limited to two small pits, located on the interior aspect of the site. Also, the S WMP and Site Map identify a sediment pond BMP that is intended to serve as a fihration device for process water from the gravel pit, and for site stormwater run-off directed to the gravel pit, prior to discharge to the agricultural ditch located south of the pit boundary. At the lime of the inspection, however, it was noted that the sediment pond was not installed onsite. The SWMP and Site Map, therefore, did not reflect site conditions noted during the inspection. The SWMP and Site Map must be updated to reflect current conditions at the site. 5. It was noted during the inspection that BMPs implemented for the berm located at the eastem perimeter of the site see photo~aph 5) were not identified in the SWMP. A vegetated buffer was noted adjacent to the eastem berm, between the berm and the pit boundary, but this BMP was not indicated in the SWMP. BMPs must be implemented to prevent the offsite discharge of sediment from all berms at the site. If the vegetated buffer is intended to be utilized as a BMP for the berm, it must be identified in the SWMP. The SWMP must be updated to identify all BMPs utilized on site. 6. It was noted during the inspection that BMPs were not implemented to prevent the erosion and discharge of sediment from the berm located at the southwest perimeter of the site (see photoeraph 61. BMPs were not implemented to prevent erosion from water run-off from the berms, and no perimeter BMPs were implemented. As a result, there was a potential for sediment discharge offsite, beyond the control ofthe operator at this location. BMPs must be implemented to prevent the offsite discharge of sediment from al] on-site berms. It was noted during the inspection that BMPs implemented for on-site stockpiled material (see photoeraph 71 were not identified in the S WMP. The stockpiled material was located approximately in the middle of the site, with a vegetated buffer between the material and the pit boundaries. All stockpiled material onsite must have BMPs in place to prevent the discharge of sediment from run-on andrun-off water. If the location of the stockpile and the vegetated buffer are intended to be utilized as BMPs for the stockpiled material, they must be identified in the SWMP. The SWMP must be updated to identify all BMPs utilized on site.
