Current through Register Vol. 24-06, March 15, 2024
(1) Monitoring.
(a) Any discharge authorized by a general
permit may be subject to such monitoring requirements as may be reasonably
required by the department, including the installation, use, and maintenance of
monitoring equipment or methods (including, where appropriate, biological
monitoring methods). These monitoring requirements would normally include but
are not limited to:
(i) Flow (in gallons per
day or other appropriate units);
(ii) All pollutants on which limitations have
been placed pursuant to WAC
173-226-070;
(iii) Pollutants (either directly or
indirectly through the use of accepted correlation coefficients or equivalent
measurements) that are subject to reduction or elimination under the terms and
conditions of the permit;
(iv)
Pollutants that the department finds could have a significant impact on the
quality of waters and sediments of the state; and
(v) Pollutants specified by the
administrator, in regulations issued pursuant to the FWPCA, as subject to
monitoring.
(b) Each
effluent flow or pollutant required to be monitored pursuant to (a) of this
subsection shall be monitored at intervals sufficiently frequent to yield data
that reasonably characterizes the nature of the discharge of the monitored
effluent flow or pollutant.
(c)
Monitoring for compliance with limitations imposed pursuant to WAC
173-226-070 shall be no less than
once per year.
(d) Variable
effluent flows and pollutant levels may be monitored at more frequent intervals
than relatively constant effluent flows and pollutant levels, which may be
monitored at less frequent intervals.
(e) Monitoring of intake water, influent to
treatment facilities, internal waste streams, and/or receiving waters may be
required by the department, to verify compliance with net discharge limitations
or removal requirements, to verify that proper waste treatment or control
practices are being maintained, or to determine the effects of the discharge on
the waters and sediments of the state.
(2) Recording of monitoring activities and
results. Any general permit which requires monitoring of an authorized
discharge shall require that:
(a) The
permittee maintain records of all information resulting from any monitoring
activities required as a condition of the application for, or as a condition of
coverage under a general permit;
(b) Any records of monitoring activities and
results shall include for all samples:
(i)
The date, exact place, and time of sampling;
(ii) The dates analyses were
performed;
(iii) Who performed the
analyses;
(iv) The analytical
techniques/methods used; and
(v)
The results of such analyses; and
(c) The permittee retain for a minimum of
five years any records of monitoring activities and all results of those
activities including all original strip chart recording for continuous
monitoring instrumentation and calibration and maintenance records. This period
of retention shall be extended during the course of any unresolved litigation
regarding the discharge of pollutants by the permittee, or when requested by
the department or regional administrator.
(3) Reporting of monitoring results.
(a) The department may require the permittee
to periodically report on the proper reporting form, the monitoring results
obtained pursuant to monitoring requirements in a general permit. In addition
to the required reporting form, the department may require submission of such
other reports as it determines to be necessary.
(b) Monitoring reports shall be signed by:
(i) In the case of corporations, a
responsible corporate officer or duly authorized representative, if such
representative is responsible for the overall operation of the facility from
which the discharge originates.
(ii) In the case of a partnership, a general
partner.
(iii) In the case of a
sole proprietorship, the proprietor.
(iv) In the case of a municipal, state, or
other public facility, either a principal executive officer, ranking elected
official, or other duly authorized employee.
(4) Except as provided in subsection (5) of
this section, all monitoring data required as a condition of a general permit,
or required as part of an application for coverage under a general permit shall
be prepared by a laboratory registered or accredited under the provisions of
chapter 173-50 WAC within one year of first being covered under a general
permit or by July 1, 1995, whichever is later.
(5) The following parameters need not be
accredited or registered:
(a) Flow;
(b) Temperature;
(c) Settleable solids;
(d) Conductivity, except that conductivity
shall be accredited if the laboratory must otherwise be registered or
accredited;
(e) pH, except that pH
shall be accredited if the laboratory must otherwise be registered or
accredited;
(f) Turbidity, except
that turbidity shall be accredited if the laboratory must otherwise be
registered or accredited; and
(g)
Parameters which are used solely for internal process control.
