Comparison document (with previous version of the report).
Slides from legislative briefing (pdf file)

• Proposed stormwater quality and quantity standards (summary)
• Quantity and quality standards (text) (later version than the one below)
• Required compensation fee or off site remediation credit for new, regulated development in “urban nps” impaired stream watersheds
• Table concerning thresholds (requested after last policy group meeting)

• For discussion: quantity and quality standards; treatment tables (substance of these tables was handed out previously, and not yet been incorporated into rule text); basin appendix; maintenance/inspection appendix (updated since discussed); ESC appendix (if further discussion needed).
• Not expected to be discussed 12/02/03 but fyi: infiltration appendix. This appendix was previously discussed and has been revised. If you have any further comments about this appendix, please email John Hopeck.

Introduction. Post construction stormwater discharges are routinely regulated by the DEP under the Stormwater Management Law and the Site Location Law. Post-construction discharges may also be regulated under the Waste Discharge laws, which was the basis for DEP receiving delegation of the federal NPDES program. As required by the Maine Stormwater Management Rules, the Bureau of Land and Water Quality has been developing a list of watersheds "most at risk" due to new development for streams, including a number that are known to be impaired due to urban stormwater runoff. Lists were previously adopted in rule (1997) for "most at risk" lakes and coastal waters. DEP will develop water quality standards that will have to be met by for developments proposed in these stream watersheds.

"Most at risk" and "impaired" streams are often located in urban areas that may be designated growth areas in municipalities, and there is concern that rules requiring stormwater quality treatment only in such watersheds will make it more expensive to develop there, creating an incentive for developers to move out of the areas where growth is desirable and into areas where sprawl is a problem. This concern brings into question whether previously developed property that is contributing pollutants should become subject to regulation in order to reduce pollutants coming from existing development, and "make room" for new development in these areas. DEP submitted a legislative proposal that would have the department report back to the Legislature on the question of whether existing development should be subject to regulation (among other changes).

After 6 years of experience implementing the Maine Stormwater Management Law, and recent MEPDES changes, the DEP also needs to address program clarifications and updates affecting Chapter 500.
