Sec. 18 AAC 83.455 - Monitoring requirements
§ 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).(Eff. 7/29/2006, Register 179; am 11/10/2007, Register 184)
