Appendix F

Requirements of Approved Total Maximum Daily Loads (TMDL).

For information about Appendix F, per the permit, see page 19 section 2.2.1 of the NHMS4GP.

“Approved TMDLs” for discharges from the permittee’s MS4 are those that have been approved by EPA as of the issuance date of this permit.

For those TMDLs that specify a wasteload allocation or other requirements either individually or categorically for the MS4 discharge, the permittee shall comply with the applicable requirements of Appendix F. Appendix F identifies, by section, the provisions and schedules the permittee shall comply with to be consistent with the terms of the approved TMDL.

The “TMDL for 158 Acid Impaired Ponds and 21 Aluminum Impaired Lakes” and the “Northeast Regional Mercury TMDL” do not specify wasteload allocations or other requirements either individually or categorically for the MS4 discharges and specify that load reductions are to be achieved through reduction in atmospheric deposition sources. View Appendix F - Requirements of Approved Total Maximum Daily Loads.

Bacteria TMDL Requirements

Pet Waste and Septic Systems (Appendix F Section II.1.a.i)

Part 2.3.3. Public Education: The permittee shall replace its Residential program with an annual message encouraging the proper management of pet waste, including noting any existing ordinances where appropriate, at a minimum.

Catchment Sampling and Investigations (Appendix F Section II.1.a.i)

Part 2.3.4 Illicit Discharge: The permittee shall implement the illicit discharge program required by this permit. Catchments draining to any waterbody impaired for bacteria or pathogens shall be designated either Problem Catchments or HIGH priority in implementation of the IDDE program.

MCM #3 IDDE Resources  

Chloride TMDL Requirements

Appendix F Section I.1

The permittee shall develop a Chloride Reduction Plan that includes specific actions designed to achieve chloride reduction on municipal roads and facilities, and on private facilities that drain to the MS4. The Chloride Reduction Plan shall be completed within one (1) year of the effective date of the permit and shall include, at a minimum: See Appendix F Sections Section I.1 for a list of specific requirements.
