The discussion around the potential installation of waterless urinals in new 40B developments emerged as a prominent topic. A member suggested mandating such installations to reduce nitrogen input from urine, which could result in a significant reduction of nitrogen contributions by as much as 40-50% from specific developments. This idea generated interest and was considered a practical move to incorporate infrastructure for urine diversion during the planning stages of high-density buildings.

Maggie McGaw voiced support for the urine diversion proposal and emphasized the importance of enforcement mechanisms for nitrogen bylaws. The committee noted the necessity for consistent enforcement across various regulations impacting water quality, recognizing that enforcement is key to achieving the desired outcomes in nitrogen reduction and water quality improvement.

Another point of discussion was the implications of the 40B regulations on local water quality initiatives. Members acknowledged the complications posed by these regulations, which supersede local but not state regulations, making it challenging to achieve Total Maximum Daily Loads (TMDLs) for nitrogen. The committee referenced the select board’s intention to engage with state representatives to reform the 40B law, advocating for changes that better account for local conditions and water quality goals. Historical context was provided, highlighting a previous unsuccessful effort to repeal 40B, with suggestions that it might be time to revisit the issue.

The committee also addressed the relationship between the Massachusetts Environmental Policy Act (MEPA) and the Department of Environmental Protection (DEP), clarifying their distinct roles in environmental reviews and watershed permit processes. Concerns were raised about the state’s indecision on environmental reviews, and discussions were confirmed with the state regarding a potential delay in submissions for watershed management plans for Little Pond and Great Pond. This would allow for a consolidated plan, streamlining the administrative process without affecting ongoing actions in Falmouth.

Attention was brought to the existing watershed plan for Pleasant Bay, which had been approved without necessitating the MEPA process due to the absence of infrastructure development. The conversation underscored the need to clarify when MEPA reviews are triggered, particularly for non-construction projects. The committee emphasized the importance of accurate data representation in watershed management plans, discussing numerical data related to infiltration and inflow allowances, sewering ratios, and zoning.

Public comments highlighted additional concerns, particularly regarding the town’s approach to reducing nitrogen levels from fertilizers. A member of the Pond Coalition questioned which department was responsible for quantifying fertilizer reduction efforts, pointing out the lack of enforcement mechanisms. This prompted a broader discussion on the town’s projections concerning fertilizer reduction’s contribution to addressing TMDLs and the effectiveness of existing bylaws.

The conversation shifted to the regulatory framework for Innovative Alternative Septic Systems (IAS) and their implementation in Falmouth, particularly in relation to the Board of Health’s mapping and regulations. There was contention over the defined areas for IAS installation, with some members suggesting that the areas were too limited. Petitions were submitted to the select board advocating for taxpayer assistance in financing IAS installations to ensure fairness between properties connected to sewers and those utilizing IAS.

Financial implications of adopting a fair system for IAS were discussed, with concerns raised about potential conflicts between the Board of Health’s regulations and the town’s watershed management plans. Members highlighted the necessity for collaboration between the committees to avoid regulatory conflicts and ensure effective management of watersheds.

The committee also deliberated on declaring the entire town a nitrogen-sensitive area, incorporating the Board of Health’s regulations to ensure compliance with nitrogen mitigation requirements. This proposal aimed to unify efforts in managing nitrogen-sensitive areas but raised questions about enforcement and public communication.

As the meeting progressed, the efficacy of current efforts was examined, with some members expressing satisfaction with improvements in Little Pond, noting cleaner conditions and the recovery of eelgrass. The importance of comprehensive monitoring of ecological recovery was emphasized, with a proposal to revisit the draft Resource Management Plan at the next meeting to align efforts with watershed plans.
