Proposed UDO Text Changes ? 2015
7.12.4.C Applicability
1. The stormwater management standards listed below are required for any new
development and/or redevelopment site that meets one or more of the following
criteria:
(A) New development of new impervious surface area that creates, or adds 5,000
square feet or greater of impervious surface, or that involves land disturbing
of 5,000 square feet or greater or,
(B) Redevelopment that includes the creation or addition of new impervious
surface area creates, replaces or adds 5,000 square feet or greater of new
impervious surface, or that involves land disturbing activity of 1 acre or
more, including projects less than 1 acre if they are part of a larger common
plan of development or sale, or,
(C) Any commercial or industrial new development or redevelopment, regardless
of size, with a SIC or NAICS that requires coverage under the State of
Georgia?s NPDES Industrial Stormwater Discharge Permitting Program, or a
hotspot use as defined below.
(D) Redevelopment sites that involve land disturbing of 5,000 square feet or
greater, but less than 1 acre.
(E) For the purposes of engineering calculations, replacement of impervious
surface shall assume that the site?s predevelopment state is ?pasture in good
condition? or equivalent.
(F) These standards will be required of all land disturbing plan applications
initially received after January 1, 2016.
2. In addition, redevelopment sites that involve land disturbing activity of
5,000 square feet or greater, but less than 1 acre, are required to meet
Minimum Standard 8 (to meet State and NPDES construction and erosion and
sediment control requirements) and are required to meet minimum standards 2, 9
and 10 to the maximum extent practicable. For sites that meet one or more of
the above criteria, the permittee shall ensure that the following minimum
standards are incorporated into the site plan:
(A) Stormwater Runoff Quality/Pollutant Reduction
Stormwater runoff shall be adequately treated prior to discharge. The
stormwater management system shall be designed to remove at least 80% of the
average annual post-development total suspended solids (TSS) load or equivalent
as defined in the Georgia Stormwater Management Manual. Compliance with this
performance standard is presumed to be met if the stormwater management system
is sized to capture and treat the water quality volume, which is defined as the
runoff volume resulting from the first 1.2 inches of rainfall from a site.
(B) Stream Channel/Aquatic Resource Protection
Steam Channel and/or Aquatic Resource Protection shall be provided by using the
following approaches: 1) 24-hour extended detention storage of the 1-year,
24-hour return frequency storm event; 2) erosion prevention measures such as
energy dissipation and velocity control; and 3) preservation of the applicable
stream buffer.
(C) Overbank Flood Protection
Downstream Overbank Flood Protection shall be provided by controlling the
post-development peak discharge rate to the predevelopment rate for the
25-year, 24-hour storm event.
(D) Extreme Flood Protection
Extreme Flood Protection shall be provided by controlling the 100-year, 24-hour
storm event such that flooding is not exacerbated.
7.12.4.F Additional Requirements
1. New development or redevelopment in critical or sensitive areas, or as
identified through a watershed plan or study namely watersheds that contribute
to Columbus?s drinking water source, Lake Oliver, or watersheds listed on the
most current 303(d) Impaired Waters list, published by the Georgia
Environmental Protection Division, may be subject to additional performance and
or regulatory criteria. Furthermore, these sites may need be required to
utilize or restrict certain structural controls in order to protect a special
resource or address certain water quality or drainage problems identified for a
drainage area/watershed.
2. This requirement for additional Best Management Practices (BMPs) or
restriction of the use of certain BMPs will be at the discretion of the
Director of Engineering or his/her designee on a case-by-case basis.
7.12.7.F Maintenance of Private Stormwater Management Facilities
1. The owner/operator of a private stormwater management facility (i.e., a
facility not accepted by the City that serves any development) shall
perpetually be responsible for the proper operation and maintenance of said
facility. Failure to operate or maintain a stormwater management facility in
accordance with this chapter shall be a violation of this Chapter. Should it
become necessary for the City to perform work (or have a private contractor
perform work on behalf of the City) in order to maintain a private facility,
then the City may place a lien against the property until full reimbursement
for the work performed by City forces, or work paid for by the City, is
recovered.
2. The owner of a private stormwater management facility shall submit an
annual maintenance report to the City. The annual report will document all
maintenance and inspection activities conducted by the owner on his/her
stormwater management facility(ies) for each calendar year. Blank maintenance
and inspection reports, provided by the City, shall be completed by the owner
or his/her designee for each facility and returned to the City no later than
January 31 of the following year. This requirement applies to all existing and
future stormwater management facilities; both inside and outside the Combined
Sewer Area and shall go into effect January 1, 2016. The first reports under
the requirement will be due by January 31, 2017. Failure to provide the City
with an adequate Annual Report by the deadline shall be a violation of this
Chapter.
3. Maintenance and Inspection standards and schedules expected by the City
mirror those found in the most recently published Georgia Stormwater Management
Manual (GSMM). Should prescribed maintenance and inspection activities and
recommended schedules not be included in the GSMM, those activities and
schedules recommended by the device?s manufacturer, at a minimum, will be
required.
7.12.14. ? Monitoring of Industrial Stormwater Dischargers
A. Industrial Stormwater Discharge Permittee Definition
1. Permittees must have a storm water discharge associated with industrial
activity from the permittee?s primary industrial activity, as identified by
Sectors A through AA and AB below.
2. Sector AB. This permit also authorizes storm water discharges under Sector
AB from any industrial activity designated by EPD where the designation is
based on the potential for contribution to a violation of a water quality
standard or for significant contribution of pollutants to Waters of the State.
Sector AB permittees must be notified by EPD that the permittee is eligible for
coverage under Sector AB of this permit.
3. Municipally owned or operated industrial facilities must comply with the
permit and monitoring requirements for all types of industrial activities that
such installations perform.
B. Applicability and Exceptions
1. Applicability
a. Applicability under this Ordinance is limited to discharges from facilities
