The
SWPPP must be
prepared before construction commences, ideally during the project planning and
design phases. It is recommended that for large sites, the SWPPP be included as
part of the bid package. Implementation of the SWPPP begins with the onset of
construction activities, as the initial phase of construction is usually
clearing and grubbing of the site, which exposes the area to uncontrolled
stormwater runoff. Inspection and maintenance of best management practices
occurs throughout the life of the construction project and until the site is
stabilized.
Development of SWPPP and SWPPP
implementation
These
phases are designed to identify SWPPP procedures at both preconstruction
(development) and construction (implementation) phases.
Development
of SWPPP
•
Collect site information
•
Develop site plan
•
Select Best Management Practices
•
Prepare a site map
•
Prepare a monitoring, inspection, and maintenance plan
Implementation
of SWPPP
The
implementation stage occurs during the commencement of construction and
consists of implementation BMPs, SWPPP review and modifications, and final
stabilization of the site.

SWPPP KY(Kentucky
Storm Water Pollution Prevention Plan) Requirements
The
Kentucky CGP mandates operators to plan and implement appropriate and adequate
practices to manage the discharge of stormwater runoff from construction
related activities. Permittees are required to develop a Storm Water Pollution
Prevention Plan (SWPPP) and implement the SWPPP at the beginning of the
construction disturbance. In accordance with Federal and state regulations, as well
as their SWPPP, owners and operators are also encouraged to develop measures
that eliminate or minimize post-construction stormwater runoff, such as
low-impact development (LID) technologies.
The
Stormwater Pollution Prevention Plan (SWPPP) must include: (1) site description
that identifies sources of pollution found on the site premises; (2) site map;
(3) erosion prevention measures; (4) sediment control measures; (5) Best
Management Practices (BMPs) to prevent the discharge of stormwater pollutants from
the construction site into water bodies of the state; (6) continual maintenance
of stormwater controls; (7) inspection schedules; and (8) plans to achieve
post-construction final stabilization.
Best Management Practices (BMPs) included in the SWPPP are required to
be appropriately selected based on specific site conditions, as well as
properly installed and maintained to effectively minimize discharges from storm
events up to and including a 2 year, 24 hour event.
Within
their Construction General Permit (CGP), The Kentucky Division of Water (DOW)
has mandated additional “protective requirements” for construction activities
discharging to “High Quality Waters” (waters requiring anti-degradation
review). Along with erosion prevention measures, sediment control measures and
site Best Management Practices (BMPs), owners or operators discharging into
high quality waters must install erosion control mats/blankets, mulch, straw
stabilized with tackifiers, buffers and retention basins capable of withstanding
a 2 year, 24 hour rain event.

A
successful SWPPP identifies the issues of concern before construction begins
and is also adaptable for the many unexpected changes that come about with
every construction project. Planning ahead is the most effective way to
minimize erosion and sedimentation during construction and reduce project
costs. A well organized and planned out SWPPP will assist in the prevention of
unnecessary permit violations and save the owner and contractor time, money,
and effort over the course of the project.
