The Chief Operator may require any Industrial User to provide, operate
and maintain, at the Industrial User's own expense, sampling, monitoring and/or
metering facilities at the point or points in the facility selected by the
Chief Operator to allow inspection, sampling, and flow measurement of discharges
to the sewerage system and/or internal piping systems. Sampling and monitoring
facilities may be located as approved by the Chief Operator to allow direct
access by POTW personnel without the necessity of notice to the Industrial
User. There shall be ample room in or near such sampling manhole or facility
to allow accurate sampling and preparation of samples for analysis. The sampling
and monitoring facilities shall be provided in accordance with the Chief Operator's
requirements and all applicable local construction standards and specifications.
Construction shall be completed within 90 days following written notification
to the Industrial User by the Chief Operator that such facilities must be
built.
At least once every two years, the Chief Operator shall evaluate whether
each significant Industrial User needs a plan to control slug discharges.
The significant Industrial User shall comply with the provisions of any such
slug control plan which the Chief Operator determines to be necessary, including,
but not limited to:
A. A description of discharge practices, including nonroutine
batch discharges;
B. A description of stored chemicals;
C. Procedures for immediately notifying the POTW of slug
discharges, including any discharge that would violate a prohibition under
40 CFR 403.5(b), with procedures for follow-up written notification within
five days; and
D. If necessary, procedures to prevent adverse impact from
accidental spills, including those procedures set forth in 40 CFR 403.8(f)(2)(v)(D).
