FROM NCC OR THEIR STAFF BEFORE ANY WORK CAN COMMENCE
NCC will be notified first and a meeting will be set up to go over plans prior to commencement
of any activity. In an emergency situation, where immediate action is necessary, the
Commission will be notified within 24 hours of the work completion, and a permanent measure
will be proposed, if necessary. The Commission will have the opportunity to review and
approve the work, approve the work with modifications or determine that an additional filing is
necessary.
Maintenance and repair of structural conveyances and appurtenant structures such as
headwalls, wingwalls, splash pads, etc…, including removal of recent culvert/bridge
blockages (sediment and/or debris). If possible, work should be completed during low
flow conditions and work shall be done in the dry. To complete work in the dry, the
water shall be dammed upstream of the culvert and the water will be pumped around the
structure into a dewatering bag to allow for filtering of sediments from the water. If work
must be conducted on a structure located over a waterway or wetland, care will be taken
to prevent material from entering the resource area.

2.5 INFORMATION PERTAINING TO THE USE OF HERBICIDES
Per 310 CMR 10.03(6)(a-c), the use of herbicides will follow the MWPA regulations as shown
below:
Any application of herbicides within any area subject to protection under the MWPA or
the buffer zone associated with a structure or facility which is existing and lawfully
located; used in the service of the public; and used to provide electric, gas, water, sewer,
telephone, telegraph, and other telecommunication services shall be presumed to
constitute work performed in the course of maintaining such structure or facility, and
shall be accorded the exemption of suck work under the MWPA, only if the application of
herbicides to that structure or facility is performed in accordance with such plans as are
required by the Department of Food and Agriculture pursuant to 333 CMR 11.00 Rights
of Way Management, effective July 10, 1987
Any application of herbicides within the buffer zone, other than as provided in 310 CMR
10.03(6)(a), shall be presumed not to alter an area subject to protection under the
MWPA, only if the work is performed in accordance with such plans as are required by
the Department of Food and Agriculture pursuant to 333 CMR 11.00 Rights of Way
Management, effective July 10, 1987. This presumption shall apply only if the person
proposing such activity has requested and obtained a determination of the boundaries of
the Buffer Zone and Areas Subject to Protection under MWPA in accordance with 310
CMR 10.05(3)(a) 1. And 2; and has submitted that determination as part of the
Vegetation Management Plan.
Any application of herbicides for management of rights of way within a riverfront area not
subject to 310 CMR 10.03(6)(a) or (b), provided the area is outside any other resource
area and qualifies under the provisions of 310 CMR 10.58(6)(a), shall be accorded an
exemption of such work under MWPA, provided that the application of herbicides is
performed in accordance with such plans as are required by the Department of Food
and Agriculture pursuant to 333 CMR 11.00: Rights of Way Management
2.6 MOSQUITO CONTROL
The practice of mosquito control has been ongoing in the City of Northampton for many years.
The chemicals/treatments used have been approved by the City’s Board of Health and are used
by other municipalities located within mosquito control districts. Likely treatment areas include
all conservation areas within the City; all wetland/swamp areas within the City, with the
exception of property owned by the Audubon Society; and all wetlands/swamps within the first
100 foot property boundaries of land owned by the Audubon Society.
ROUTINE MAINTENANCE AND REPAIR ACTIVITIES
BUNDLED NOTICE OF INTENT
SUBMITTED TO THE NORTHAMPTON CONSERVATION COMMISSION
2.9
DPW is currently not treating for mosquitoes, but may begin treatment in the future. Should
treatment resume, DPW would use BTI (Bacillus thuringiensis israelensis), a bacteria to treat
mosquito larvae in municipal wetlands and catch basins. Treatment is weather dependent, but
usually happens in early spring. Mosquito control beyond municipal catch basins and wetlands
will only be done at the request of the Board of Health and/or nuisance complaints from
residents. Application shall be conducted by licensed pesticide applicators only, in accordance
with safe handling and application guidelines.
2.7 NOTIFICATION AND SEQUENCE OF WORK PROTOCOL
1. Notification of the Conservation Commission
DPW shall notify the Conservation Commission planner within 48 hours of commencement
of any maintenance project that will occur within a resource area except for paved Riverfront
Area or gravel roads within Bordering Land Subject to Flooding. DPW will provide NCC with
a brief project description and location of work area.
2. Evaluation of Sensitive Areas
Before DPW begins any work that will occur within a resource area except for paved
Riverfront Area and/or gravel roads within Bordering Land Subject to Flooding and work
listed under Category V, DPW’s Senior Environmental Scientist will evaluate whether the
area is located within mapped habitat, a certified vernal pool and/or Outstanding Resource
Water. NCC will be notified first via the Conservation Planner and if necessary a meeting
will be scheduled to go over proposed work prior to the start of the maintenance activity.
The Commission will have the opportunity to review and approve the work, approve the
work with modifications, or determine that an additional filing is necessary.
3. On – site Meeting
The DPW Superintendent or his/her representative shall meet with the Conservation
Commission at the location of the proposed work for an on-site meeting within 48 hours of
notification of the start of work. The entire Commission need not be present. The
Superintendent or representative will present a verbal summary of proposed work,
demonstrate that a copy of the BOOC is present at the site and that all individuals
participating in the work have reviewed the BOOC. If the project is of a minor nature the
Commission may elect that no site meeting is necessary.
4. Wetland and Other Resource Area Identification and Delineation
The DPW will rely on the Senior Environmental Scientist to evaluate and identify the location
of all resource areas protected under the MWPA and its regulations, as well as the local
wetlands ordinance. DPW realizes that the Conservation Commission may require that the
delineation be completed prior to proceeding with certain maintenance activities. This
identification of resource area boundaries shall include those areas within the project limits
of work, and those areas where work is within 50 feet of a resource area. The DPW will
ROUTINE MAINTENANCE AND REPAIR ACTIVITIES
BUNDLED NOTICE OF INTENT

2.10
place wetland flagging tape, flags and any other methods necessary to locate these areas in
the field. To the extent possible, these markers shall remain in place during construction.
5. Erosion and Sedimentation Controls
Appropriate soil erosion, sediment and turbidity controls must be used and maintained in
effective operating condition during maintenance activities, and all exposed soil and other
fills must be permanently stabilized at the earliest practicable date. Appropriate soil erosion
and sediment controls are management measures, practices and devices, such as phased
construction, installation of sediment control barriers (i.e., silt fence, vegetated filter strips,
geotextile silt fences, filter tubes, erosion control mixes, straw bales or other devices)
downhill of all exposed areas, retention of existing vegetated buffers, application of
temporary mulching during construction, and permanent seeding and stabilization, etc.
Erosion, sediment and turbidity controls shall be capable of preventing erosion, of collecting
sediment, suspended and floating materials, and of filtering fine sediment. Erosion and
sedimentation controls should be selected, designed, installed and maintained by reference
to “Massachusetts Erosion and Sediment Control Guidelines for Urban and Suburban
Areas: A Guide for Planners, Designers, and Municipal Officials” (MADEP March 1997).
Temporary soil erosion, sediment and turbidity controls shall be removed promptly upon
completion of work, but not until all disturbed areas are permanently stabilized. The
sediment collected by these devices shall be removed and placed at an upland location in a
manner that will prevent its later erosion into a waterway or wetland. Controls may be left in
place if they are biodegradable, appropriate, and flows, animal passage, etc...are not
disrupted. Biodegradable controls left in place, such as rolled erosion control products
(e.g.., mulch control netting, erosion control blankets, turf mats, mulch socks, fiber rolls,
wattles, etc.), must be composed of 100% biodegradable material.
