The committee reported progress on the offshore outfall project, an endeavor designed to enhance water quality by directing treated wastewater further offshore, thus mitigating nitrogen pollution in local water bodies. At the center of this discussion was the pending Environmental Notification Form (ENF), an essential document in the regulatory review process. The ENF will outline the project’s scope, objectives, and background, including detailed assessments such as the two-year baseline monitoring program in Nantucket Sound, which incorporates benthic and eelgrass surveys. These efforts have gained acknowledgment from the Massachusetts Division of Marine Fisheries and the coastal zone management office for enriching existing data sets.

The meeting also highlighted a detailed timeline for the project’s progression, with a town meeting scheduled to request $590,000 for drafting the environmental impact report and conceptual design. This funding is important for developing the 30% design plans necessary for subsequent permitting processes. The committee noted that the construction of the pipeline from the shore to the diffusers would be quicker than the segment from the treatment plant to the discharge point. The project aims to start construction by 2028, with an anticipated completion of the permitting process, including the National Pollutant Discharge Elimination System (NPDES) permits, by the end of 2027.

In addition to the outfall project, the committee discussed the broader implications of nitrogen management in Falmouth. The conversation acknowledged the need to advance timelines for watershed permit applications, particularly in response to recent algal blooms. The committee considered accelerating the permitting process for watersheds like Woy Bay Eel Pond, Great Pond, and Little Pond, emphasizing the groundwork established by earlier studies and plans, such as the 2022 Great Pond Targeted Watershed Management Plan.

The potential integration of Innovative Alternative (IA) systems in nitrogen-sensitive areas was another point of focus. These systems could reduce nitrogen loads and are seen as a componet of the comprehensive strategy to meet total maximum daily load (TMDL) requirements. The committee is contemplating recommending to the Board of Health a trigger for mandatory IA systems in these areas, though recognizing that this may face resistance from residents. However, it was noted that such installations could make homeowners eligible for state tax credits, offering financial incentives.

Further discussions broached the possibility of incorporating urine diverting toilets as part of the nitrogen reduction strategy. A pilot project, funded by a grant, is set to install these systems in approximately 25 homes within nitrogen-sensitive watersheds. The committee debated whether participants should receive exemptions from future sewer connection requirements, a matter complicated by the ongoing Masttec research project, which is expected to provide critical insights into the effectiveness of these systems. The necessity of waiting for empirical data before offering such incentives was emphasized, with some committee members cautioning against making premature commitments.

The meeting concluded with logistical updates, including planning for an informational session for property owners in the Great Pond Phase 1 sewer project area and a mention of a local scout seeking engagement for a merit badge related to water quality issues. Additionally, routine approvals were made for previous meeting minutes and regulatory approvals for the Great Pond project.
