Borough of Avondale MS4
Stormwater Discharge to Municipal Storm Water Systems
(NPDES – Phase II)
Please note, effective March 10, 2003 the Borough of Avondale
is subject to the new Federal National Pollutant Discharge
Elimination System – Phase II mandates for Municipal
Separate Storm Sewer Systems (MS4). This means the Borough
will endeavor to monitor all earth disturbance and other contributions
to the Municipal Storm Sewer System within the Borough Limits
to assist in protection of quality of its creeks and rivers.
Any illegal contribution to the Borough’s storm sewer
system will be noted and the violators will be issued a warning
to desist and correct the violation. If the violation continues
the violators will be subject to penalties.
As part of this program, stormwater inlets, or catch basins,
in the Borough have been marked DUMP NO WASTE – DRAINS
TO STREAM.
The quality of our waterways is everyone’s concern
and mutual consideration and cooperation is expected to maintain
the quality of Pennsylvania’s waterways.
Stormwater discharge is exactly what it says, water generated
from a storm event. No other runoff should be directed to
the stormwater system. The Borough has an ordinance (No. 222, enacted on 5-2-08) that prohibits non-stormwater discharges, with certain possible exemptions. These are permitted
only if they do not pose a significant contribution to pollution
to surface waters of the Commonwealth.
We appreciate your understanding and hope for mutual cooperation
to ensure compliance with these new regulations.
