Senior Specialist Observations Facility Documentation/Training Does the facility have a Stormwater Pollution Prevention Plan (SWPPP) or similar document? Is it facility -specific? Yes, they do have a SWPPP. The SWPPP is site specific and covers all aspects of this site, although it covers a wide range of items not associated with this site. What type of stormwater training do facility employees receive? How often? Employees receive detailed training that covers all aspects of the SWPPP. The training is performed once a year by video, which Jason Dunigan played for us. Inspector Training/Knowledge What type of stormwater training does the M54 inspector receive? How often? The stormwater inspector receives the same training that is given to all the employees. Did the M54 inspector appear knowledgeable about Permit requirements for pollution prevention and good housekeeping? The MS4 inspector appeared to be knowledgeable about permit requirements and had a detailed guidance document for that required portion of the permit. Did the MS4 inspector appear knowledgeable about stormwater pollution prevention and good housekeeping? The MS4 inspector appeared to be knowledgeable about stormwater pollution prevention and good housekeeping and used a checklist developed specifically for that purpose. Inspection Procedures Does the MS4 inspector's process include the use of a checklist or other standardized form? Yes, The Inspector had a standardized form (Form 19) that was specifically developed for, and found in, their site -specific Stormwater Pollution Prevention Plan. The only documented checklist that was available was for the first quarter of 2012 NCS000250_Raleigh M54 Audit_20190701 Page 03 of 04 Site Visit Evaluation: Municipal Facility No. 1 Does the MS4 inspector's process include taking photos? No photos were taken during inspection and none were provided. Does the MS4 inspector's process include reviewing the facility's SWPPP (or similar document)? Yes, the facility has a very detailed SWPPP outline, but the last update was July 14, 2017. Does the MS4 Inspector's process include walking the entire facility and inspecting all points of discharge? Yes, the MS4 inspector walked what was believed to be the entire permitted boundary, but a portion of the facility is being used as a staging and parking area by the Roadside Environmental Division. That activity, being located within the parcel boundary, should be inspected as well as part of the permit with any outlets included for sampling. Did the MS4 inspector miss any obvious areas of concern? If so, explain: Yes, there was an unspecified number of 5-gallon buckets, some partially buried, containing petroleum residue on the south east side of the property that should have been removed and properly disposed. Does the MS4 inspector's process include presenting the inspection findings to the facility contact? The MS4 inspector, Jason Dunigan, is -the site contact. Inspection Results Did the facility inspection result in any corrective actions to be implemented? If so, for what issue(s)? The area utilized by Roadside Environmental as a staging area was not included as part of the area to be inspected so no inspection data or monitoring was performed for that area. An illicit discharge occurred while the audit was taking place by a DOT contractor who was off-loading their vac truck contents into the on -site sediment basin. The M54 inspector states that this happens on occasion, and they have trouble preventing it. Open 5-gallon buckets, some partially buried, with petroleum product residue were found on the south-eastern side of the property below the silt basin and have been there some time. If compliance corrective actions were identified, -what timeline for correction/follow-up was provided? We asked that the petroleum contaminated 5-gallon buckets be cleaned up and they immediately did so. We also asked that corrective actions be taken immediately to remove the water off-loaded into the silt basin by the DOT contractor from the vacuum truck Notes/Comments/Recommendations We recommend that the site map be updated to include the area used by Roadside Environmental as a staging area and that the inspection protocol include that area as part of the inspection and that any additional sample points be identified and monitored. The illicit discharge that occurred should be reported to DLR within 30 days, documented in the (SWPPP) and on a tracking database, and provide an update of the corrective actions taken as required by the permit. Dig out and clean up all discarded petroleum contaminated 5-gallon buckets found on the south-east side of the property below the silt basin and have them disposed of properly NCS000250_Raleigh MS4 Audit�20190701 Page 04 of 04
