C. 
The following discharges are authorized unless they are determined to be significant contributors to pollution to the waters of this commonwealth:
(1) 
Discharges or flows from firefighting activities.
(2) 
Discharges from potable water sources, including water line flushing and fire hydrant flushing if such discharges do not contain detectable concentrations of total residual chlorine (TRC).
(3) 
Noncontaminated irrigation water, water from lawn maintenance, landscape drainage and flows from riparian habitats and wetlands.
(4) 
Diverted stream flows and springs.

When it is more advantageous to connect roof drains directly to streets, storm sewers or roadside swales, such connections may be permitted by the municipality on a case-by-case basis.
D. 
Roof drains shall discharge to infiltration areas or vegetative BMPs to the maximum extent practicable.
