Drive Fletcher, NC 28732 Subject: Relief from Monthly Stormwater Sampling Stormwater Permit # NCG030055 Meritor Heavy Vehicle Systems Henderson County Dear Mr. Laughter: .ROY COOPER Governor MICHAEL S. REGAN Secretary TRACY DAVIS Director The Division has reviewed your request for regulatory relief from monthly stormwater sampling. The facility was inspected on March 28, 2017, and was found to be in compliance.with the tiered response actions and other conditions of the NCG030000 General Permit. As noted in the follow-up email received on March 30, 2017, from Hank Laughter, Meritor Heavy Vehicle Systems LLC has performed inspections, modified and implemented additional stormwater pollution prevention measures and procedures. Also, the facility has installed sheds for storing dunnage; reviewed SDS database for material used onsite in production with zinc and copper content; installed a new sluice valve; store decommissioned equipment under roof or under cover when awaiting transfer offsite, eta As observed during the inspection and due to facility actions taken regarding investigating and correcting exceedances, the Division is granting the facility regulatory relief from the tier responses for copper and zinc. Upon receipt of this letter, the subject facility may resume the permit specified semi-annual analytical monitoring for the remainder of the current permit term which ends on October 31, 2017. This decision applies only to copper and zinc benchmarks and is valid until October 31, 2018. A benchmark exceedance of any other parameter listed in your permit will trigger the tiered response actions as described in the general permit., You must notify this office, in writing, within five business days if you become aware of any significant source of copper and zinc at your facility that has the potential to be exposed to stormwater. The relief granted in this letter is contingent upon the current industrial practices at Meritor Heavy Vehicle Systems LLC. If industrial practices change and copper or zinc does become a significant stormwater exposure risk or significant copper or zinc values have been recorded during a regular sampling event, then this office reserves the right to withdraw this decision and reinstate the permit specified tiered response or other actions that may be warranted by the new set of circumstances.
