NOI – An NOI must be submitted to the federal EPA, before application for NPDES permits to both the EPA and MADEP can be completed.
- The NOI must be submitted at > 14 days before construction activities begin
- Filing for an NOI requires the preparer and/or new certifying official to register an account in EPA’s Central Data Exchange.
- Click here to submit NOI
- Once registered, they must contact the eNOI processing center to have the old information linked to our new account.
- The NOI serves as the College’s notice to the permitting authority(s) that Amherst College intends for the discharge to be authorized under the terms and conditions of that general permit, and that all of the requirements of the NPDES permit and College’s SWPPP will be followed.
- Under the CWA, the EPA authorizes the NPDES permit program to states to perform administrative, enforcement and permitting aspects of the NPDES requirements.
- A NPDES permit is required if discharging from a point source into the waters of the United States.
- NPDES permits are issued by the states that have obtained EPA approval.
- Massachusetts is not an EPA approved state, so permits are issued by EPA, New England.
- The permit should be obtained by persons that have “control over the construction plans, sites and specifications, and/or has day-day operational control of the site, including activities necessary to implement the SWPPP”
- The NPDES permit provides two levels of control to bodies of water
- Technology-based limits
- Water Quality- based limits
- The NPDES permit is typically licensed to a facility to discharge a specified amount of a pollutant into a receiving water under conditions. The three (3) types of NPDES permits are;
- Construction Activities
- Applicable to Amherst College if the construction site > 1 acre, or is part of a common development plan that will ultimately disturb > 1 acre.
- Is the NPDES permit required for the project?
- Industrial Activities
- Municipal (MS4) Sources
- The NPDES permit is in effect from time of completion for up to five (5) years
- NPDES permits can be renewed (reissued) at any time after the permit holder applies.
- In addition, NPDES permits can be administratively extended if the College reapplies > 180 days before the permit expires.
SWPPP – In order to complete the above referenced documents (NOI and NPDES permits) the College or other requesting facility / operator must have a SWPPP, and Stormwater Management Plan. The Plan shall follow BMP’s for both construction activities and ongoing operations and maintenance, as identified here-in.
Stormwater Management Standards
- In addition to the requirements of the federal Environmental Protection Agency (EPA) under 40 CFR, Part 122, the Massachusetts Stormwater Management Standards have been incorporated into the Commonwealth’s Wetland Protection Act Regulations, 310 CMR 10.05 and the Water Quality Certification Regulations, 314 CMR 9.06.
- In order to properly manage Stormwater run-off and lessen the burden to brooks, lakes, ponds and rivers, Amherst College will follow best management practices during construction and maintenance activities, which will include the proper selection and use of materials that might be discharged to wetlands (navigable water ways) and bodies of water that might adversely affect fish, plant and other wildlife.
- One of the most significant sources of Stormwater run-off is from rain and snowmelt from impervious surfaces. When not managed properly, these run-offs could alter drainage, increase peak discharge rates and volumes, reduce recharge to wetlands and streams, and increase discharge of pollutants to areas where this could be detrimental.
- The following stormwater strategies are designed to include consideration of environmentally sensitive site designs, Low Impact Development (LID) techniques to minimize impervious surface and land disturbance, source controls and pollution prevention, structural BMP’s, construction site erosion and sediment control, and long term operation and maintenance of stormwater management systems.
- Stormwater Standards now indicate that Stormwater Systems shall…
- not discharge untreated stormwater directly to or cause erosion in wetlands or waters of the Commonwealth
- shall be designed so that the post-development peak discharge rates do not exceed pre-development peak discharge rates.
- eliminate or minimize loss of annual recharge to groundwater through the use of infiltration system measures including;
- environmentally sensitive site design
- low impact development techniques
- stormwater best management practices
- proper maintenance and operations plans and practices
- be designed to remove 80% of the average annual post construction load of Total Suspended Solids (TSS), which is the dry-weight of suspended particles, which are not dissolved in the water. In order to accomplish the above, BMP such as these are utilized;
- identify and maintain source control and pollution prevention activities
- size to capture the determined volume of run-off
- follow pretreatment guidelines identified in the Massachusetts Stormwater Handbook perimeter controls(handbook)
- when required for land with higher potential pollutant loads use source control and pollution prevention in accordance with the handbook to eliminate or reduce the discharge of stormwater runoff to the extent practical.
- use of specific source control and pollution prevention measures and the specific structural stormwater BMP’s determined by the MADEP to be suitable for managing discharges to such areas, as indicated in the handbook.
- a discharge is near a critical area, if there is a strong likelihood of a significant impact occurring to an area designated as protected, or a priority habitat for species and wildlife.
- Stormwater discharges to Outstanding and Special Resource Waters shall be removed and set back from receiving water/wetland and receive best practical method of treatment
- if within a Zone II or Interim Wellhead Protection Area of a public water supply, and storm discharges near or to any other critical area, such as to the east and south of the College require the use of a specific source control and pollution prevention measures, and the BMP determined by the Department for managing discharges to those areas, as indicated in the handbook.
- not applicable, as Amherst College is not part of a redevelopment project
- have a plan to control construction related impacts including erosion, sedimentation and other pollutant sources during construction, and that land disturbance activities (construction period erosion, sedimentation, and pollution prevention plan) shall be developed and implemented
- insure that long-term operations and maintenance plans shall be developed and implemented to ensure that stormwater management systems function as designed, and

- Land disturbance activities include demolition, construction, clearing, excavation, grading, filling, and reconstruction.
- For projects subject to Wetlands jurisdiction, construction-related activities will identify ways to control erosion, sedimentation, and have a stormwater management plan that identifies the person(s) responsible for implementing, inspecting and maintaining the plan as required.
- The plan shall be approved by the Conservation Commission, until the site is fully stabilized and the temporary erosion and sedimentation controls are removed.
- Projects that disturb one acre of land or more are required to;
- have NPDES Construction General Permit issued by EPA, and
- have the required a Stormwater Pollution Plan (SWPPP)
- for ease of consistency and to avoid duplication, the College has prepared this all-inclusive document that satisfies the SWPPP requirements of the Construction General Permit
- For all projects that require coverage under the Construction General Permit, the issuing authority shall require submission of the SWPPP before land disturbance commences.
- For construction projects, including demolition activities that require the use of an architect, engineer or similar, the plans for the project shall include designs of, and approval stormwater management
- The construction period erosion, sedimentation and pollution prevention plan must identify all stormwater management activities that are needed during land disturbance and construction, including source control and pollution prevention measures, BMPs to address erosion and sedimentation, stabilization measures, and procedures for operating and maintaining the BMPs, including response to wet weather events and frost.
- The plan shall include a schedule for sequencing construction and stormwater management activities that minimizes land disturbance by ensuring that vegetation is preserved to the extent practicable, and disturbed portions of the site are stabilized as soon as possible.
- BMPs used during construction are designed to control higher concentrations of sediment typical of construction activities and run-off

- Erosion Control Requirements
- Contractors working on Amherst College property shall be familiar with the College SWPPP and shall utilize appropriate techniques identified here-in, or by the site engineer to control runoff as referenced in the Amherst College Stormwater Pollution Prevention Plan. The SWPPP outlines best management practices for control of stormwater runoff, erosion control, stockpile management and inspection reports.
- Stormwater Manager – Construction
- During construction activities, it is the responsibility of the General Contractor to identify a Stormwater Manager.
- Stormwater Managers must be competent, having knowledge of stormwater pollution prevention guidelines, erosion and sediments controls, hay bales and silt fences, and the inspection requirements for construction site activities. When a SWPPP deficiency is identified, it shall be corrected immediately.
- The site Stormwater Manager is responsible for;
- Daily Inspections of the construction activities that would be directly related to run-off from the project, including the maintenance of the trap rock entry/exit areas for vehicles, erosion control, stockpiles, as well as the maintenance of catch basins and detention ponds on the site.
- Problems identified, such as dirt, mud, salt and sand leaving the site by catch basin or street must be immediately corrected.
- Weekly Inspections of the entire site, using either the Amherst College inspection checklist, or a similar "approved" inspection report acceptable to the owner and the Town of Amherst.
- Inspection reports must be maintained on site, available for review by the owner and regulatory agencies, including the Town of Amherst and MASSDEP.
- Significant Weather Event Inspections are formal inspections of the construction site that must be performed after significant rain, wind or other damaging event that would adversely affect the stormwater control measures for the site.
- When necessary, the Stormwater Manager, through the General Contractor shall perform required corrective actions, which include, but are not limited to;
- Catch basin cleaning
- Street sweeping

- turf reinforcement mats
- silt fence or fiber rolls on moderate slopes
- should be installed on level contours spaced at 10 – 20’ intervals
- Storm Drain Protection
- Should be used for storm drains both inside and outside the construction area if there is a possibility that storm water could impact one or both of these receptors. These filters include;
- block and gravel
- inlet filters
- rock and sand filled bags
- silt fences
- Perimeter Controls
- Are designed to maintain natural areas and supplement them with silt fence and fiber rolls around the perimeter of the site to prevent sediment and soil from leaving the site.
- These controls should be installed on the downslope perimeter of the site. They are not required around the entire site.
- These are designed to protect streams, waterways and wetlands
- They are only effective in small areas and should not be used to contain a flow of stormwater, or other substantial water flow.
- Installation techniques;
- leave space for maintenance between toe of slope and silt fence roll
- trench the silt fence on the uphill side 6” deep and 6” wide
- install stakes on the downhill side of the fence or roll
- curve end of silt fence or fiber roll up-gradient to help contain run-off
- remove sediment when it reaches 1/3 the height of the fence
- replace the silt fence or roll where it is worn, torn or otherwise damaged
- retrench or replace any silt fence or roll that is not properly anchored to the ground
- Sediment Retention and Dewatering Control (on-site)
- For smaller construction sites, the use of sediment barriers is permissible.
- For larger construction sites, the use of temporary sediment basins and traps should be considered.
- Sediment retention is designed to detain sediment-laden run-off for the period of time necessary to allow sediment to settle, without negatively impacting the protected areas.
- Dewatering practices are used to remove groundwater or accumulated rain water from excavated areas.
- Water can be pumped from these areas to a temporary or permanent sedimentation basin or area completely enclosed by a silt fence in a flat vegetated area where discharges can infiltrate the ground.
- If this practice is not possible, because water exceeds the capacity of the silt fencing or site, contact the office of Environmental Health & Safety for other appropriate water disposal options.
- Never discharge dirty/muddy water into storm drains, tributaries or wetlands, unless the sediment has been removed.
- Exit Sites on Construction Sites
- Since vehicles have the ability to track sediment off the construction site onto streets from which stormwater will flow, entrances and/or exit areas for vehicles should protected in a way that prevents debris, sediment, sand etc., from leaving the site.
- Construction exits (> 50’, depending on the size of project) should have large crushed rock to remove some sediment from the tires, and when necessary, when required by the College, have a washing station (on the rock exit) to further reduce the potential for sediment leaving the site.
- Cement / Concrete trucks are not permitted to wash concrete from vehicle or chute to ground, except into appropriate areas designed specifically for that purpose.
