MS4 PHASE II PERMIT PUBLIC HEARINGS
04.22.10 12:02 PMTDEC has scheduled a series of public hearings to accept comments on the 2010 Draft Phase II MS4 NPDES General Permit. Check out the draft by clicking here. A Municipal Separate Stormwater Sewer System (MS4) is simply the series of ditches and watercourses not tied into the sanitary sewer that eventually discharge to a stream. The permit will involve requirements for local governments, but these requirements will in turn be imposed on all entities that have a stormwater discharge. This includes industrial discharges as well as construction. The permit will have significant impact on the construction industry as performance standards for post construction runoff, including requirements for runoff reduction and incentives for green infrastructure. This is an NPDES permit that more than 80 local governments use to comply with stormwater requirements. All four of Tennessee’s largest municipalities and TDOT have an individual MS4 permit. There are many significant differences in the permit from the existing one, which will be discussed in another post. The permit makes substantial changes and clarifications from the prior MS4 permit which is now in effect. Here is the schedule of public hearings:
