The Superintendent is authorized and empowered to enter into agreements, issue permits, or to make other arrangements for handling and treating industrial wastes which, in his/her opinion, are amenable to collection in the Town's POTW and treatment in the Town's POTW treatment plant. The Superintendent also reserves the right to establish in these Rules general local limits for industrial wastewater discharges. The Superintendent may also establish individual user limitations, which may be expressed either as concentration-based limits or mass-based limits. The Superintendent may also develop discharge limitations and other permit requirements applicable to generators and transporters of holding tank wastes or other hauled wastes discharged to the POTW. Such limits shall be developed using methods acceptable to the EPA.
National categorical standards found in 40 CFR Chapter I, Subchapter N, Parts 405 to 471 are hereby incorporated into these Rules.
A.
Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the Superintendent may impose equivalent concentration or mass limits in accordance with 40 CFR 403.6(c).
B.
When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the Superintendent shall impose an alternate limit using the combined waste stream formula in 40 CFR 403.6(e).
C.
A user may obtain a variance from a categorical pretreatment standard if the user can prove, pursuant to the procedural and substantive provisions in 40 CFR 403.13, that factors relating to its discharge are fundamentally different from the factors considered by the EPA when developing the categorical pretreatment standard.
D.
A CIU may obtain a net/gross adjustment to a categorical standard in accordance with 40 CFR 403.15.
E.
Upon the effective date of the federal categorical pretreatment standards for a particular industrial subcategory, the categorical standard, if more stringent than the limitations imposed under this chapter for sources in that subcategory, shall immediately supersede the limitations imposed under this chapter.
F.
State requirements and limitations on discharges shall apply in any case where they are more stringent than federal requirements and limitations or those contained in these Rules.
Users shall provide necessary wastewater treatment as required to comply with these Rules and any applicable pretreatment standards. Users shall achieve compliance with all federal categorical pretreatment standards within the time limitations as specified by the federal pretreatment regulations. Any facilities required to pretreat wastewater to a level acceptable to the Superintendent shall be provided, operated, and maintained at the user's expense. If the pretreatment or equalization of waste flows is required, the design and installation of the plants and equipment shall be stamped by an engineer registered in the Commonwealth of Massachusetts and subject to the requirements of these Rules and all applicable codes, ordinances, and laws. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the Superintendent for review, and shall be approved by the Superintendent before construction of the facility. The review of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the Superintendent under the provisions of these Rules. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be acceptable to the Superintendent prior to the user's initiation of the changes. The transportation and/or disposal of sludges generated by pretreatment shall be subject to applicable federal, state and local regulations. The industrial user shall be responsible for documenting the transportation and/or disposal of all pretreatment sludges. Receipts and other documentation shall be kept for a minimum of three years and shall be made available to the Superintendent upon request.
Where preliminary treatment or flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the user at his expense.
No user shall increase the use of process water in an attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the limitations contained in any pretreatment standard, or in any other pollutant-specific limitation developed by the Town or state, unless expressly authorized to do so by the applicable standard or limitation.
Each user shall provide protection from accidental discharge of prohibited materials or slug discharges of other substances regulated by these Rules. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the owner's or user's own cost and expense. The Town shall evaluate at least once every two years whether each existing significant industrial user will be required to develop such plan. In the case of an industrial user being designated as a significant industrial user, the Town will evaluate the need for a slug control plan within one year. Each significant industrial user is required to notify the POTW immediately of any changes at its facility affecting potential for slug discharge in accordance with 40 CFR 403.8(f)(2)(vi). In the case of an accidental discharge or slug loading, it is the responsibility of the user to immediately telephone and notify the POTW of the incident. The notification shall include location of discharge, type of waste, concentration and volume, and corrective actions being taken by the user. The Superintendent shall evaluate whether each SIU needs an accidental discharge/slug discharge control plan or other action to control slug discharges. The Superintendent may require any user to develop, submit for approval, and implement such a plan or take such other action that may be necessary to control slug discharges. Alternatively, the Superintendent may develop such a plan for any user. An accidental discharge/slug discharge control plan shall address, at a minimum, the following:
A.
Description of discharge practices, including nonroutine batch discharges;
B.
Description of stored chemicals;
C.
Procedures for immediately notifying the Superintendent of any accidental or slug discharge;
D.
Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents, and/or measures and equipment for emergency response.
E.
Written notice. Within five days following an accidental discharge or slug loading the user shall submit to the Superintendent a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage, or other liability which may be incurred as a result of damage to the POTW, fish kills, or any other damage to person or property; nor shall such notification relieve the user of any civil penalties or other liability which may be imposed by these Rules or other applicable law.
Septic tank waste may be introduced into the POTW only at locations designated by the Superintendent and at such times as established by the Superintendent. Such waste shall not violate these Rules or any other requirements established by the Town. A waste hauler discharge permit application must be completed and submitted to the Superintendent. Hauled industrial wastes are prohibited. Every person licensed to transport the aforementioned substances shall be entitled to collect from the owner, occupant, or person having charge of the premises from which he has removed any of the substances such compensation as shall be fixed by the rules of the Department of Public Health, whether such removal is made upon the application of such owner, occupant or agent, or by order of the Department of Public Health.
