To Whom It May Concern,
I am writing to oppose amendments to 10-144 CMR Chapter 241, Maine Subsurface Wastewater Disposal Rules. Specifically, I am urging the Department to keep existing soil suitability standards within the shoreland zone for first time septic systems in place in order to protect our valuable and vulnerable lakes and ponds.
A small amount of fill, big enough to install a septic system, will not make a lot poorly suited for development become more suitable. The system as well as the associated development that comes with it (like roads, driveways, and roofs) will result in increased stormwater runoff. Stormwater runoff is the primary means for excess phosphorus, a nutrient that feeds unhealthy algae blooms and degrades water quality, to reach our lakes and ponds.
Expanding septic systems, and the development that comes with it, on sites with unsuitable soils will pose an unacceptable risk to lake water quality and wildlife habitat.
I urge you to delete this standard revision from the proposed rule changes and keep the requirement that fill material in the shoreland zone must have been placed before 1974 to be considered for a first-time septic system.
Thank you for the opportunity to comment on this proposal.
