Users shall make wastewater acceptable under the limitations
established herein before discharging into any community sewer. Any
facilities required to pretreat wastewater to a level acceptable to
the agency shall be provided and maintained at the user's expense.
Detailed plans showing the pretreatment facilities and operation procedures
shall be submitted to the agency for review and shall be approved
by the agency before construction of the facility. The review and
approval 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 complying with the provisions of this chapter.
Any subsequent changes in the pretreatment facilities or method of
operation shall be reported to and be approved by the agency.
Special agreements and arrangements between the agency and any
person or agencies may be established when, in the opinion of the
agency, unusual or extraordinary circumstances compel special terms
and conditions. No such special agreement or arrangement, however,
shall have the effect of modifying or revising any effluent limitations
established in accordance with the Federal Act unless such a revision
is granted in accordance with mechanisms established under 40 CFR
Part 403.7.
In addition to agency personnel, employees from the United States
Environmental Protection agency and the New York State Department
of Environmental Conservation shall be given access for the purpose
of inspection, observation, measurement, sampling and testing.
