Water Act or this ordinance:

The prohibition shall not apply to any nonstormwater discharge permitted
under an NPDES permit, waiver, or waste discharge order issued to
the discharger and administered by the State of Connecticut under
the authority of the Federal Environmental Protection Agency, provided
that the discharger is in full compliance with all requirements of
the permit, waiver, or order and other applicable laws and regulations,
and provided that written approval has been granted by the Town of
New Canaan for any discharge to the storm drain system.
(3)
With written concurrence of the Connecticut Department of Environmental
Protection, the Town of New Canaan may exempt in writing other nonstormwater

A.
The construction, use, maintenance or continued existence of illicit
connections to the storm drain system is prohibited.
B.
This prohibition expressly includes, without limitation, illicit
connections made in the past, regardless of whether the connection
was permissible under law or practices applicable or prevailing at
the time of connection.
No person shall throw, deposit, leave, maintain, keep, or permit
to be thrown, deposited, left, or maintained, in or upon any public
or private property, driveway, parking area, street, alley, sidewalk,
component of the storm drain system, or water of the United States,
any refuse, rubbish, garbage, litter, or other discarded or abandoned
objects, articles, and accumulations, so that the same may cause or
contribute to pollution. Wastes deposited in streets in proper waste
receptacles for the purposes of collection are exempted from this
prohibition.
Any person subject to an industrial or construction activity
NPDES stormwater discharge permit shall comply with all provisions
of such permit. Proof of compliance with said permit may be required

condition of a subdivision map, site plan, building permit, or development
or improvement plan; upon inspection of the facility; during any enforcement
proceeding or action; or for any other reasonable cause.
