Section ENV.04.12 — Monitoring

(a) The Division shall take such samples as may be necessary to enable it to determine the quality of every reasonably accessible segment of reservation waters. In sampling such waters the Division shall give consideration to characteristics such as those listed in Section ENV.04.02(b), but if pollution is suspected the sampling shall not be limited or restricted by reason of the fact that no water quality standard has been promulgated for the suspected type of pollution.

(b) As to every segment of reservation waters so sampled, the Division shall endeavor to determine the nature and amount of each pollutant, whether a new or different water quality standard is needed, the source of each pollutant, the place where such pollutant enters the water, and the names and addresses of each person responsible for or in control of each entry.

(c) As to each separate pollution source identified, the Division shall:

(1) Determine what control regulation is applicable, if any;

(2) Determine whether the discharge is covered by a permit and whether any condition of the permit is being violated; and

(3) Determine what further control measures with respect to such pollution source are practicable.

(d) The Division shall inform the Commission of any unusual problem which creates difficulties in abating pollution.
