SUBJECT: Ordinance No. 1600 -- Stormwater Regulation ordinance
-- Second Reading
MEETING BATE: Monday, April 2, 2007 -- Regular Council Meeting
BACKGROUND: On January 22P 2007 Susie Turner, our staff stormwater
engineer, advised the City Council of the current Federal and State stormwater
permitting requirements with which the City is expected to comply. The Council
reviewed, at that time, the draft ordinance which staff is recommending will meet
the MS4 criteria. This draft ordinance was made available to the public for
comment and staff considered the written comment and recommended some
amendments to the ordinance based upon that comment. A public hearing was also
held on February 20, 2007. The public comment period was extended to the March
19, 2007 Council meeting date. No further comment has been received. Council
passed Ordinance No. 1600 on first reading
RECOMMENDATION: MENDATION: That Council consider and pass Ordinance No. 1600 on
second reading.
FISCAL EFFECTS: The fiscal impact of ordinance No. 1600 was already
anticipated and staff has been hired to administer the regulatory requirements
placed upon the City by the State and Federal governments. Ordinance No. 1600 is
the reflection of these requirements.

ORDINANCE NO.1600
AN ORDINANCE REGULATING AND CONTROLLING THE DESIGN,
CONSTRUCTION, USE, AND MAINTENANCE OF ANY DEVELOPMENT OR OTHER
.ACTIVITY WHICH DISTURBS OR BREADS THE TOPSOIL OR RESULTS IN THE
MOVEMENT OF EARTH ON LAND IN THE CITY TO COMPLY WITH THE NPDES
PHASE II STORMWATER PROGRAM OF THE ENVIRONMENTAL PROTECTION
AGENCY AS ADMINISTERED BY THE MONTANA STATE DEPARTMENT OF
ENVIRONMENTAL QUALITY AND DECLARING AN EFFECTIVE DATE.
WHEREAS during the construction and land disturbance process, soil is the most vulnerable
to erosion by wind and water which endangers grater resources by reducing water
quality and causing the siltation of aquatic habitat for fish and other desirable
species; and
WHEREAS deposition of eroded soil also necessitates repair of sewers and ditches, and the
dredging of lakes; and
WHEREAS clearing and grading during construction also causes the loss of native vegetation
necessary for terrestrial and aquatic habitat, which provides a healthy living
environment for citizens of the city; and
WHEREAS management of wastes from construction sites is also important in preventing
polluted stormwater runoff from a site; and
WHEREAS the purpose of regulating, and controlling the design, construction, use, and
maintenance of any development or other activity which disturbs or breaks the
topsoil or results in the movement of earth on land in the city is to safeguard
persons, protect property, prevent damage to the environment and promote the
public welfare, as well as meet the requirements set forth in the NPDES Phase 11
Storm Water Program of the Environmental Protection Agency as administered
by the Montana State Department of Environmental Quality.
