WAC 173-220-210
Monitoring, recording and reporting. (1)
Monitoring.
(a) Any discharge authorized by a 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:
(i) Flow (in gallons per day);
(ii) Pollutants (either directly or indirectly through the
use of accepted correlation coefficients or equivalent
measurements) which are subject to reduction or elimination under
the terms and conditions of the permit;
(iii) Pollutants which the department finds could have a
significant impact on the quality of surface waters; and
(iv) 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 which reasonably
characterizes the nature of the discharge of the monitored
effluent flow or pollutant.
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.
(c) Monitoring of intake water, influent to treatment
facilities, internal waste streams, and/or receiving waters may
be required when determined necessary 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 surface waters of the state.
(2) Recording of monitoring activities and results. Any
permit which requires monitoring of the authorized discharge
shall require that:
(a) The permittee shall maintain records of all information
resulting from any monitoring activities required of him in his
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 shall be required to retain for a minimum
of three years any records of monitoring activities and results
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 permittee shall periodically report (at a frequency
of not less than once per year) on the proper reporting form, the
monitoring results obtained pursuant to monitoring requirements
in a permit. In addition to the required reporting form, the
department at its discretion may require submission of such other
results as it determines to be necessary.
(b) Monitoring reports shall be signed by:
(i) In the case of corporations, by a responsible corporate
officer or his 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, by a general partner.
(iii) In the case of a sole proprietorship, by the
proprietor.
(iv) In the case of a municipal, state or other public
facility, by either a principal executive officer, ranking
elected official, or other duly authorized employee.
(4) Use of registered or accredited laboratories:
(a) Except as established in (c) of this subsection,
monitoring data submitted to the department in accordance with
this chapter shall be prepared by a laboratory accredited under
the provisions of chapter 173-50 WAC no later than indicated by
the appropriate date below:
July 1, 1992, major dischargers;
July 1, 1993, all permittees with a permitted average flow
rate greater than five million gallons per day.
These requirements are effective and binding on all
permittees under the authority of rule, regardless of whether
they have been included as conditions of a permit.
(b) Except as established in (c) of this subsection,
monitoring data submitted to the department in accordance with
this chapter shall be prepared by a laboratory registered or
accredited under the provisions of chapter 173-50 WAC no later
than July 1, 1994, for all NPDES permittees not covered under (a)
of this subsection.
These requirements are effective and binding on all
permittees under the authority of rule, regardless of whether
they have been included as conditions of a permit.
(c) The following parameters need not be accredited or
registered:
(i) Flow;
(ii) Temperature;
(iii) Settleable solids;
(iv) Conductivity, except that conductivity shall be
accredited if the laboratory must otherwise be registered or
accredited;
(v) pH, except that pH shall be accredited if the laboratory
must otherwise be registered or accredited;
(vi) Turbidity, except that turbidity shall be accredited if
the laboratory must otherwise be registered or accredited; and
(vii) Parameters which are used solely for internal process
control.
