Inspection Summary:
On July 11, 2019 this facility was inspected for compliance and to review the industrial process for permit renewal. I met with
Amber Matson, Travis McKinney and Melvin Graham on site, I also teleconferenced with John Bolden, Environmental
Engineer. The following items were noted during the inspection:
1) The Stormwater Pollution Prevention Plan (SWPPP) was not maintained on site. A SWPPP was eventually made
available through email. The permittee is directed to immediately begin maintaining and implementing a SWPPP on site, as
required by the Permit.
2) Appropriate Tier Response had not been implemented on site. The permittee is directed to immediately begin monthly
monitoring and follow all response procedures as specified in the Permit for Tier Response.
3) Aluminum was discussed a great deal during the inspection. Mr. Boldin is pursuing the removal of Aluminum from the
permit due to the process used to analyze it. That information is still being considered. The permittee is directed to continue
including Aluminum in all monitoring parameters until informed otherwise by the department.
4) The BMPs used to reduce the amount of entrained mica in the stormwater runoff were full at the time of the inspection.
the permittee is directed to evaluate the potential for increased maintenance and cleaning out of those BMPs, and include
that evaluation in the Preventative maintenance section of the on -site SWPPP.
The permittee is advised that the facility is currently in Tier 3 status, and to respond as required by the Permit.
Please give the above actions your immediate attention, and respond as outlined in the enclosed Notice of Violation.
If you have any questions, please contact this office at [phone]
