Box: 590 Raleigh,NC 27602 Subject: Draft NPDES Permit Permit NC0030759 Smith Creek Resource Recovery Facility Wake County Grade IV Biological WPCS SIC Code 4952 , Dear Mr. Kiviniemi: Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility. Please review this draft carefully to ensure thorough understanding of the requirements and conditions it contains. There are several changes from the existing permit, including the following: • At the request of the Permittee,'the facility's name has been changed from Smith Creek WWTP to Smith Creek Resource Recovery Facility(RRF). • Based on the facility's address provided in your renewal application,the facility's address on the•Permit Cover Sheet and Supplement to Permit Cover Sheet has been updated to 8505 Ligon Mill Road, Wake forest,NC 27587. • The treatment component list in Supplement to Permit Cover Sheet has been updated, please review the treatment component list carefully. • Please note, Special Condition A. (6.) will be removed with the next permit renewal. Permittees are required to obtain a non-discharge permit for onsite spray irrigation. • Upstream and effluent total hardness quarterly monitoring have been added to the permit for all flow tiers (3.0 and 6.0 MGD) as required by the implementation guidance for the new dissolved metal standards [ See A. (1.) and A. (2.)]. • The Permittee reported Total Silver at less than detection,with detection levels<5.0 µg/L. The Permittee's permit discharge requirement is 0.925 µg/L for flow tier of 3 MGD and 0.492 µg/L for flow tier of 6 MGD for Total Silver. DWR's laboratory identifies the Practical Quantification Limit(PQL)for Total Silver as approximately 1 µg/L. In this case, the Permittee should test for Total Silver down to the recommended PQL and as long as the Permittee reports effluent Total Silver less than the PQL or a lower reporting level of the procedure, the Permittee will be considered in compliance with its permit discharge requirement (limit). As stated above, in accordance with 15A NCAC 2B .0500 the State of North Carolina I Environmental Quality I Water Resources 1617 Mail Service Center I Raleigh,North Carolina 27699-1617 919 807 6300 Page 12 Permittee shall test for Total Silver down to the lower reporting level of the procedure. The Division can modify this permit and add a limit or add limits during the next renewal if this regulation is not satisfied. In the meantime, quarterly monitoring and reporting for Total Silver has been added to the permit for both flow tiers(3.0 and 6.0 MGD) [ See A. (1.) and A. (2.)]. • Based on the Mercury TMDL evaluation, a Mercury Minimization Plan (MMP) requirement has been added to this permit renewal. See Special Condition A. (9). Please note that the Permittee shall develop and implement an MMP during this permit term. The MMP shall be developed within 180 days of the NPDES Permit Effective Date, and shall be available for inspection on-site. A sample MMP was developed through a stakeholder review process and has been placed on the Division website for guidance (http://portal.ncdenr.org/web/wq/swp/ps/npdes, under Model Mercury Minimization Plan). • Instream monitoring requirements have been added to Effluent Limitations and Monitoring Requirements [See A. (1.) and A. (2.)] and Special condition for instream monitoring requirements has been removed from the permit. • Effluent pollutant scans requirements have been added to Effluent Limitations and Monitoring Requirements [See A. (1.) and A. (2.)]. Special condition A. (7.) to include specific three years in which the effluent Pollutant Scan shall be performed (2020, 2021, 2022) and submitted with you)-next renewal application per Federal Regulations [40 CFR 122.21(j)(4)]has been added to the permit. In addition, at the end of the Special Condition, 2nd species Toxicity Testing Requirements for municipal permit renewals per Federal Regulations [40 CFR 122.21(j)(5)] have been added. • Some of the wording has changed in Special Condition A. (5.), Chronic Toxicity Permit Limit, please review each paragraph carefully. • Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program reports. The requirement to continue reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report(eDMR) internet application has been added to your NPDES permit [See Special Condition A. (10.)]. • Parameter codes have been added to the Effluent Limitations and Monitoring Requirements [ See A. (1.) and A. (2.)]. • Regulatory citations have been added to the permit. The NPDES Standard Conditions (Parts II, III, and IV) are not included with this draft. They can be found at the following link if you Would like to review them in conjunction with this draft permit. http://portal.ncdenr.org/c/document_library/get file?uuid=b32a66-541 c-4cf5-8ba6- 03e381 edb2da&groupld=38364 Concurrent with this notification the Division is publishing a notice in a newspaper having circulation in the general Wake Count area, soliciting public comments on this draft permit.
