The Nantucket Board of Health voted Oct. 16 to schedule a public hearing Nov. 20 on updated regulations for the Hammock Pond Watershed District and the Wellhead Protection District, moving the draft forward for public comment and legal review.
Board members said the revisions are intended to standardize rules across multiple protection districts and to tighten provisions on nitrogen-loading, system setbacks and what qualifies as an "enhanced nitrogen-reducing system." Carrie (board member) said she had added a clearer definition stating an enhanced system must be "capable of reducing nitrogen in wastewater to a minimum of 19 milligrams per liter from an average influent concentration of 40 milligrams per liter," language that appears throughout the draft where those systems are required.
Board and staff discussion focused on three implementation items: (1) removing redundant provisions and clarifying overlap with Title 5 requirements; (2) refining the property-transfer inspection wording to make clear that inspections must occur at the time of transfer or within two years prior to transfer; and (3) strengthening variance language so variances would be limited to rare and exceptional circumstances. John (Health Department staff) and Carrie said they would forward board comments to town counsel for legal review before the public hearing if possible; staff asked board members to submit editorial and substantive comments within the next few days to avoid serial back-and-forth outside an open meeting.
The board voted to schedule the public hearing for Nov. 20 and said the hearing may be continued if town-counsel review is not complete. The vote starts a public-notice timetable that will include advertisement and a formal hearing process as required by local rules.
Why it matters: The draft regulations would affect septic design, transfer inspection requirements and nitrogen-loading credits across designated protection districts; tightening those rules is part of the town's effort to protect sensitive water bodies and public-water supply wells.
Next steps: Staff will circulate a revised draft to the board, seek town-counsel review, advertise the hearing and accept public testimony at the Nov. 20 meeting; the board may continue the hearing if legal review or additional edits require more time.
Quote in context: "I insisted on having a comment about bedroom credits," Carrie said, adding that bedroom-credit language must be explicit. Board members asked that corrections and substantive comments be sent to staff so they can be consolidated for council review and a public hearing notice.
