New Compendium on MS4 Permitting Approaches:
EPA has released a new compendium of MS4 Permitting Approaches which talks about water quality based requirements (Part 3). It gives a snapshot of the MS4 permit provisions focused on water quality based requirements for specific pollutants consistent with the approved TMDLs. It also includes provisions to protect impaired waters prior to TMDL development or to achieve other water quality based objectives.
Draft Guidance on Voluntary Long-Term Planning for Stormwater Management:
EPA has prepared a draft guide describing a process to develop a comprehensive long-term community stormwater plan that integrates stormwater management with communities’ broader plans for economic development, infrastructure investment and environmental compliance. This draft guidance is released to assist states and local authorities in developing and implementing effective long-term stormwater plans.
EPA will continue to work with five pilot communities in Pennsylvania, Iowa, Mississippi, New Hampshire and New Mexico to test the draft guide and create stormwater plans to serve as national models.
Dental Amalgam Rule:
The effective date of the final rule was July 14, 2017 and the dental office category regulation is codified in 40 CFR Part 441. According to this rule, dental offices that place or remove amalgam must operate and maintain amalgam separators and shall not discharge scrap amalgam or use certain kinds of line cleaners.
Existing offices must comply by July 14, 2020. The rule is effective immediately (July 14, 2017) for new offices. The sources must submit a one-time compliance report as directed by the control authorities i.e., POTW or State or EPA depending upon the approval of pretreatment program. The compliance report must be submitted to the control authority no later than October 12, 2020 and new sources must submit the report no later than 90 days following the introduction of wastewater into a POTW. EPA has not prepared a template of the compliance report at this time.
