Upon the promulgation of the Federal Categorical Pretreatment
Standards for a particular industrial subcategory, the federal standard,
if more stringent than limitations imposed under this Part 2 for sources
in that subcategory, shall immediately supersede the limitations imposed
under this Part 2. The Superintendent shall notify all affected users
of the applicable reporting requirements under 40 CFR 403.12.
Where the Town's wastewater treatment system achieves consistent
removal of pollutants limited by Federal Pretreatment Standards, the
Town may apply to the Approval Authority for modification of specific
limits in the Federal Pretreatment Standards. "Consistent Removal"
shall mean reduction in the amount if pollutant or alteration of the
nature of the pollutant by the wastewater treatment system to a less
toxic or harmless state in the effluent which is achieved by the system
as reported by analyses of 95% of the samples taken when measured
according to the procedures set forth in Section 403.7(c)(2) of Title
40 of the Code of Federal Regulations, Part 403, General Pretreatment
Regulations for Existing and New Sources of Pollution, promulgated
pursuant to the Act. The Town may then modify pollutant discharge
limits in the federal pretreatment standards if the requirements contained
in 40 CFR, Part 403, Section 403.7, are fulfilled and prior approval
from the Approval Authority is obtained.

Requirements and limitations on discharges established under
the Rhode Island Pollution Discharge Elimination System shall apply
in any case where they are more stringent than federal requirements
and limitations or those in this Part 2.
The Town reserves the right to establish by ordinance more stringent limitations or requirements on discharges to the wastewater disposal system if deemed necessary to comply with the objectives presented in §
206-55 of this article.
No User shall ever increase the use of process water or, in
any way, attempt to dilute a discharge as a partial or complete substitute
for adequate treatment to achieve compliance with the limitations
contained in the Federal Categorical Pretreatment Standards, or in
any other pollution-specific limitations developed by the Town or
state.
Each user shall provide protection from accidental discharge
of prohibited materials or other substances regulated by this Part
2. Facilities to prevent accidental discharge of prohibited materials
shall be provided and maintained at the owner or user's own cost and
expense. Detailed plans showing facilities and operating procedures
to provide this protection shall be submitted to the Director for
review, and shall be approved by the Director before construction
of the facility. All existing users shall complete such a plan within
90 days of the adoption of this Part 2. No user who commences contribution
to the POTW after the effective date of this Part 2 shall be permitted
to introduce pollutants into the system until accidental discharge
procedures have been approved by the Director. Review and approval
of such plans and operating procedures shall not relieve the Industrial
user from the responsibility to modify the user's facility as necessary
to meet the requirements of this Part 2. In the case of an accidental
discharge, 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.
Within five days following an accidental discharge, 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 fines, civil penalties, or other liability
which may be imposed by this article or other applicable laws.
A notice shall be permanently posted on the user's bulletin
board or other prominent place advising employees whom to call in
the event of a dangerous discharge. Employers shall insure that all
employees who may cause or suffer such a dangerous discharge to occur
are advised of the emergency notification procedure.
As defined in 40 CFR 403.16.
