Yarmouth Site Plan Review Committee

SUBJECT: Wells 10 & 11 Seasonal PFAS Treatment Project Site Plan Review Hearing (10/14/2025)
Comment Responses
To whom it may concern,
Enclosed are responses to comments shared by the Site Plan Review Committee during the site plan
review hearing on 10/14/2025:
Building:
Comment: “Per Table 202.5, P10 use in a residential zoning district will require a SP from the ZBA.”
Response: An application for a Special Permit for P10 use in a residential zone will be submitted to the
Zoning Board of Appeals for a hearing.
Community Development & Planning:
Comment: “Ensure adequate screening from Forest Road.”
Response: There is ample foliage to provide screening from Forest Road. See attached photos 1-3 taken
from Forest Road looking toward the Well 10 site.
Engineering:
Comment: “Inspect and repair 24” CMP culvert as needed”
Response: See attached photos 4 and 5 of the 24” CMP culvert. The culvert will be supported during the
proposed water main installation. Replacement of the culvert would require excavation work in the two
wetland areas that it connects. These wetlands are federally regulated as waters of the United States.
This work would require permitting with the USACOE which is outside of the scope of this project.
Additionally, the timeline required to obtain these federal permits would jeopardize the Town’s SRF
funding by extending the current schedule beyond the required SRF deadlines.
Comment: “Water Department to provide maintenance of infiltration basin”
Response: The Yarmouth Water Department will maintain the infiltration basin once it is placed into
operation.
Fire:
Comment: “Propane storage will require a permit from the fire department. Emergency pull station will
be required for KOH and maintained along with signage for Chemical Storage (KOH).”
Response: The project specifications require the contractor selected during the bidding phase to apply
for all necessary permits from the Fire Department. The KOH chemical feed infrastructure is being
partially replaced-in-kind as a part of this project, not substantially changed, and emergency procedures
are not being modified as part of this project scope. We do not believe that modifications to the
emergency systems are required.
Health:
Comment: “Will any of the buildings have any bathrooms or hand washing or eye washing stations? If so
what kind of wastewater treatment will there be?”
Response: There are no new buildings being constructed as part of the project.
Health – Hazardous Materials:
Comment: “Are we correct in understanding that: (1) the fuel source involved is propane; (2) there are
no additional hazardous materials involved with the project other than the 90-gallon KOH day tank; (3)
the existing 1500-gallon KOH tank has secondary containment in the form of the countersunk concrete
floor of the building?”
Response: 1) Yes, the emergency generator will be fueled by propane; 2) The 90-gallon day tank
previously existed at the site but had been relocated to another facility since Well 10 was removed from
service. The replacement of the 90-gallon day tank does not represent new or increased storage of
hazardous material, it is required to restore the facility to its original operating condition; 3) Yes, the
existing 1,500-gallon KOH bulk tank has secondary containment in the form of the countersunk concrete
floor of the building. See attached photo 6 for the existing secondary containment.
Comment: “Does the new 90-gallon KOH day tank have secondary containment in the form of a double-
walled tank or placement within the countersunk concrete floor of the building?”
Response: Yes, the replacement 90-gallon KOH day tank is located in the countersunk concrete floor
secondary containment adjacent to the existing 1500-gallon KOH bulk tank, which has sufficient volume
to contain the full volume of both tanks in accordance with MassDEP guidelines (see attached photo 6).
Comment: “Will there be any waste materials generated by the project other than spent filters from the
PFAS treatment system?”
Response: No other wastes will be generated by the project.
Comment: “Are the spent filters from the PFAS treatment system hazardous or nonhazardous waste;
how will they be disposed of and how often will they be changed and disposed?”
Response: Adsorption media used to remove PFAS is not considered hazardous waste under current
federal regulations. GAC adsorption media is typically not disposed of, it is regenerated at licensed
facilities and returned to the site for repeated use. It can also be disposed of at appropriate landfill
facilities; however, this is not a cost-effective approach.
If you have any questions about this information or wish to discuss the project, please feel free to
