[HISTORY: Adopted by the Board of Health of the Town of Groton 4-3-2000, effective 7-1-2000. Amendments noted where applicable.]
Floor drains in industrial and commercial facilities are often tied to a system leading to a leaching structure (e.g., dry well, cesspool, leach field) or a septic system; and
Poor management practices and accidental and/or intentional discharges may lead petroleum and other toxic or hazardous materials into these drainage systems in facilities managing these products; and
Improper maintenance or inappropriate use of these systems may allow the passage of contaminants or pollutants entering the drain to discharge from the leaching structure or septic system to the ground; and
Discharges of hazardous wastes and other pollutants to floor drains leading to leaching structures and septic systems have repeatedly threatened surface and groundwater quality throughout Massachusetts; and
Surface and groundwater resources in the Town of Groton contribute to the Town's drinking water supplies;
The Town of Groton adopts the following regulation, under its authority as specified in § 279-2, as a preventative measure for the purposes of:
The Town of Groton Board of Health adopts the following regulation pursuant to authorization granted by MGL C. 111, §§ 31 and 122. The regulation shall apply, as specified herein, to all applicable facilities, existing and new, within the Town of Groton.
For the purposes of this regulation, the following words and phrases shall have the following meanings:
- COMMERCIAL AND INDUSTRIAL FACILITY
- A public or private establishment where the principal use is the supply, sale, and/or manufacture of services, products, or information, including but not limited to: manufacturing, processing, or other industrial operations; service or retail establishments; printing or publishing establishments; research and development facilities; small- or large-quantity generators of hazardous waste; laboratories; hospitals.
- The Massachusetts Department of Environmental Protection.
- The accidental or intentional disposal, injection, dumping, spilling, leaking, incineration, or placing of toxic or hazardous material or waste upon or into any land or water so that such hazardous waste or any constituent thereof may enter the land or waters of the commonwealth. Discharge includes, without limitation, leakage of such materials from failed or discarded containers or storage systems and disposal of such materials into any on-site leaching structure or sewage disposal systems.
- FLOOR DRAIN
- An intended drainage point on a floor constructed to be otherwise impervious which serves as the point of entry into any subsurface drainage, treatment, disposal, containment, or other plumbing system.
- LEACHING STRUCTURE
- Any subsurface structure through which a fluid that is introduced will pass and enter the environment, including, but not limited to, dry wells, leaching catch basins, cesspools, leach fields, and oil/water separators that are not watertight.
- OIL/WATER SEPARATOR
- A device designed and installed so as to separate and retain petroleum-based oil or grease, flammable wastes as well as sand and particles from normal wastes while permitting normal sewage or liquid wastes to discharge into the drainage system by gravity. Other common names for such systems include "MDC traps," "gasoline and sand traps," "grit and oil separators," "grease traps," and "interceptors."
- TOXIC OR HAZARDOUS MATERIAL
- Any substance or mixture of physical, chemical, or infectious characteristics posing a significant, actual, or potential hazard to water supplies or other hazards to human health if such substance or mixture were discharged to land or water of the Town of Groton. Toxic or hazardous materials include, without limitation, synthetic organic chemicals, petroleum products, heavy metals, radioactive or infectious wastes, acids and alkalis, and all substances defined as toxic or hazardous under MGL C. 21C and 21E or Massachusetts Hazardous Waste Regulation (310 CMR 30.000), and also include such products as solvents, thinners, and pesticides in quantities greater than normal household use.
- USE OF TOXIC OR HAZARDOUS MATERIAL

With the exception of discharges that have received (or have applied and will receive) a Department-issued permit prior to the effective date of this regulation, no floor drain(s) shall be allowed to discharge, with or without pretreatment (such as an oil/water separator), to the ground, a leaching structure, or septic system in any industrial or commercial facility if such floor drain is located in either:
An industrial or commercial process area;
A petroleum, toxic, or hazardous materials and/or waste storage area; or
A leased facility without either Subsection A or B of this section, but in which the potential for a change of use of the property to a use which does have either Subsection A or B is, in the opinion of the Board of Health or its agent, sufficient to warrant the elimination of the ground discharge at the present.
The owner of a facility in operation prior to the effective date of this regulation with a prohibited (as defined under § 279-4) floor drain system shall:
Disconnect and plug all applicable inlets to and outlets from (where possible) applicable leaching structures, oil/water separators, and/or septic systems;
Remove all existing sludge in oil/water separators, septic systems, and, where accessible, leaching structures. Any sludge determined to be a hazardous waste shall be disposed of in accordance with state hazardous waste regulations (310 CMR 30.000).

Connected to a municipal sanitary sewer line, if available, or other sewer lines connected to a treatment plant licensed to receive such wastes, with all applicable Department and local permits; or
Permanently sealed. (Any facility sealing a drain shall be required to submit for approval to the Board of Health a hazardous waste management plan detailing the means of collecting, storing, and disposing of any hazardous waste generated by this facility, including any spill or other discharge of hazardous materials or wastes.)
Any oil/water separator remaining in use shall be monitored weekly, cleaned not less than every 90 days, and restored to proper conditions after cleaning so as to ensure proper functioning.

The effective date of this regulation shall be July 1, 2000.
Owners/Operators of a facility affected by this regulation shall comply with all of its provisions within 120 days of the effective date;
All applicable discharges to the leaching structures and septic systems shall be discontinued immediately through temporary isolation or sealing of the floor drain.
