The objectives of this article are to:
(1) Reduce the impact of post-construction discharge of stormwater on
receiving waters; and
(2) Reduce stormwater runoff rates and volumes, soil erosion and nonpoint
source pollution, wherever possible, through use of best management
practices as promulgated by the Maine Department of Environmental
Protection pursuant to its Chapters 500 and 502 Rules, and ensure
that these management controls are properly maintained and pose no
threat to public safety.
For the purposes of this article, the terms listed below are
defined as follows:
APPLICANT
A person with requisite right, title or interest or an agent
for such person who has filed an application for new development or
redevelopment that requires a post-construction stormwater management
plan under this article.
BEST MANAGEMENT PRACTICES (BMP)
Schedules of activities, prohibitions of practices, maintenance
procedures, and other management practices to prevent or reduce the
pollution of waters of the state. BMPs also include treatment requirements,
treatment devices and structures, operating procedures, and practices
to control plant site runoff, spillage or leaks, sludge or waste disposal,
or drainage from raw material storage.
CITY
The City of Biddeford.
CLEAN WATER ACT
The Federal Water Pollution Control Act (33 U.S.C. § 1251
et seq., also known as the "Clean Water Act"), and any subsequent
amendments thereto.
CONSTRUCTION ACTIVITY
Construction activity including one acre or more of disturbed
area. Construction activity also includes activity with less than
one acre of total land disturbed area if that area is part of a subdivision
that will ultimately disturb an area equal to or greater than one
acre.
DISCHARGE
Any spilling, leaking, pumping, pouring, emptying, dumping,
disposing or other addition of pollutants to waters of the state.

ditch, channel, tunnel, conduit, well, discrete fissure, container,
rolling stock, concentrated animal feeding operation or vessel or
other floating craft, from which pollutants are or may be discharged.
DISTURBED AREA
Clearing, grading and excavation. Mere cutting of trees,
without grubbing, stump removal, disturbance or exposure of soil is
not considered "disturbed area." "Disturbed area" does not include
routine maintenance but does include redevelopment. "Routine maintenance"
is maintenance performed to maintain the original line and grade,
hydraulic capacity, and original purpose of land or improvements thereon.
ENFORCEMENT AUTHORITY
The Code Enforcement Officer or other person(s) or department
designated by the City to administer and enforce this article.

Conveyances for stormwater, including, but not limited to,
roads with drainage systems, municipal streets, catch basins, curbs,
gutters, ditches, human-made channels or storm drains (other than
publicly owned treatment works and combined sewers) owned or operated
by any municipality, sewer or sewage district, fire district, state
agency or federal agency or other public entity that discharges directly
to surface waters of the state.
NEW DEVELOPMENT
Any construction activity on unimproved premises and for
purposes of this article includes "redevelopment" defined below.
PERSON
Any individual, firm, corporation, municipality, town, Quasi-municipal
Corporation, state agency or federal agency or other legal entity.
POLLUTANT
Dredged spoil, solid waste, junk, incinerator residue, sewage,

or redevelopment to meet the standards of this article and approved
by the municipal permitting authority.

REGULATED SMALL MS4
Any small MS4 regulated by the State of Maine General Permit
for the Discharge of Stormwater from Small Municipal Separate Storm
Sewer Systems (General Permit), including all those located partially
or entirely within an urbanized area (UA) and those additional small
MS4s located outside a UA that as of the issuance of the General Permit
have been designated by the DEP as regulated small MS4s.
SMALL MUNICIPAL SEPARATE STORM SEWER SYSTEM or SMALL MS4
Any MS4 that is not already covered by the Phase I MS4 stormwater
