Sec. 860.5. Other considerations

(a) Combined sewers.

Any new facility or project combining sanitary or industrial waste with stormwater drainage which would have a substantial effect on the quality of waters of the basin shall not be permitted, whether or not any such project or facility discharges into an existing combined system.

(b) Access and reports.

(1) The commission, or its duly authorized representatives, shall have access, at reasonable hours, to observe and inspect waste treatment facilities and to collect samples for analyses.

(2) Upon written request, waste treatment facility operation reports shall be submitted to the commission.

(c) Zones.

The Delaware River and Bay and their tributaries may be divided into zones which will facilitate the management of surface and underground water quality.

(d) Streamflow.

Numerical stream quality objectives are based on a minimum consecutive 7-day flow with a 10-year recurrence interval unless otherwise specified.

(e) Requests for modification of stream quality objectives.

The commission will consider requests to modify the stream quality objectives for toxic pollutants based upon site-specific factors. Such requests shall provide a demonstration of the site-specific differences in the physical, chemical or biological characteristics of the area in question, through the submission of substantial scientific data and analysis. The demonstration shall also include the proposed alternate stream quality objectives. The methodology and form of the demonstration shall be approved by the commission.
