RE: Annual Stormwater Management Permit Certification
Yarmouth File No. SW2025-002
Boston Gas Company LNG Facility
127 Whites Path, South Yarmouth, Massachusetts
Dear Members of the Yarmouth Conservation Commission,
Pursuant to Condition 23(iv) of the Stormwater Management Permit issued for the above-
referenced project, this letter serves as the Owner's Annual Certification.
As of the date of this certification, no site work, land disturbance, clearing, grading, demolition,
or construction activities associated with the approved South Yarmouth LNG Tank Replacement
Project have commenced. Accordingly, no temporary or permanent stormwater management
best management practices (BMPs) have been installed or placed into operation.
Because construction has not yet begun, no operation or maintenance activities associated with
the approved stormwater management system have been required or performed during the
previous twelve-month period. Likewise, no stormwater control measures have been placed into
service that would require inspection, repair, maintenance, sediment removal, or replacement.
During the reporting period, the project has remained in compliance with the approved
Stormwater Management Permit and associated plans and documents. The approved Operation
and Maintenance Plan and Stormwater Pollution Prevention Plan remains in effect and will be
implemented upon commencement of construction and operation of the stormwater
management system.
Construction is presently anticipated to commence in early 2027. Prior to the start of any site
work, Boston Gas Company d/b/a National Grid will contact the Conservation Commission to
schedule the required pre-construction meeting in accordance with Condition 11 of the
Stormwater Management Permit and will provide the SWPPP as required by Special Condition 1.
