18 AAC 83.455 - Monitoring requirements
(a) A permit must
include the following requirements for monitoring and reporting:
(1) provisions concerning the proper use,
maintenance, and installation of appropriate monitoring equipment or methods,
including biological monitoring methods;
(2) the type, intervals and frequency of
monitoring required to yield data that are representative of the monitored
activity, including continuous monitoring when appropriate;
(3) provisions for reporting the results of
monitoring, including frequency, appropriate for the regulated activity based
on the impact of that activity and as specified in (b) - (e) of this
section;
(4) monitoring sufficient
to assure compliance with permit limitations for
(A) the mass or other measurement specified
in the permit for each pollutant limited in the permit;
(B) the volume of effluent discharged from
each outfall; and
(C) other
appropriate measurements, including
(i)
pollutants in internal waste streams under
18 AAC 83.550;
(ii) pollutants in intake water for net
limitations under
18 AAC 83.545;
(iii) frequency, rate of discharge, and other
requirements for noncontinuous discharges under
18 AAC 83.535; and
(iv) pollutants subject to notification
requirements under
18 AAC 83.610; and
(5) analyses of
pollutants using test procedures approved under 40 C.F.R. Part 136, adopted by
reference in
18 AAC 83.010, for pollutants with
approved test procedures, and using test procedures specified in the permit for
pollutants without approved methods.
(b) Except as provided in (d) and (e) of this
section, the department will establish requirements to report monitoring
results, including the frequency of required reports, on a case-by-case basis
depending on the nature and effect of the discharge. The department will
require a monitoring report from a permittee under this subsection at least
once a year.
(c) The department
will establish requirements to report monitoring results, including the
frequency of required reports, for storm water discharges associated with
industrial activity that are subject to an effluent limitation guideline, on a
case-by-case basis depending on the nature and effect of the discharge. The
department will require monitoring results from a permittee under this
subsection at least once a year.
(d) Except as provided in (c) of this
section, the department will establish monitoring report requirements for storm
water discharges associated with industrial activity, on a case-by-case basis,
with a frequency dependent on the nature and effect of the discharge, but in no
case less than once a year. A permit for a discharge described in this
subsection must, at a minimum, require the discharger to
(1) conduct an annual inspection of the
facility site to identify areas contributing to a storm water discharge
associated with industrial activity and evaluate whether measures to reduce
pollutant loadings identified in a storm water pollution prevention plan are
adequate and properly implemented in accordance with the terms of the permit or
whether additional control measures are needed;
(2) maintain for a period of three years a
record summarizing the results of the inspection and a certification that the
facility is in compliance with the plan and the permit, and identifying any
incidents of non-compliance;
(3)
sign and certify the report in compliance with
18 AAC 83.385; and
(4) submit, once every three years, a
registered professional engineer's certification that the facility is in
compliance with the permit, or to comply with alternative requirements approved
by the department if an annual inspection is impracticable for a discharger of
storm water associated with industrial activity from inactive mining
operations.
(e) A permit
that does not require monitoring results reports at least annually must require
the permittee to report, at least annually, all instances of noncompliance not
reported under
18 AAC 83.410(f).
