									The Mississippi Department of Environmental Quality (MDEQ) recognized certain types
of activities that consistently resulted in the issuance of similar environmental permits.
Therefore, the Mississippi Environmental Quality Permit Board issued a series of State
Wide General Permits, each of which address environmental concerns for specific types
of businesses or business operations. Thus providing a simplified application and
permitting process for coverage under the applicable General Permit. This brochure
provides a discussion of each type of General Permit currently available through the
MDEQ.

Storm Water General Permits

Small Construction General Permit

The Small Construction General Permit applies to the discharge of storm water from
construction operations involving the disturbance of one (1) acre or more but less than
five (5) acres of soils. This acreage amount includes the total land area disturbed over the
full length of the project. Routine maintenance conducted to maintain the original line
and grade of existing access roads, ditches, and channels do not require coverage under a
storm water permit. The Small Construction Notice of Intent (SCNOI) is the form used
to apply for coverage under the State Wide General Permit. Upon completing this form
and the required Storm Water Pollution Prevention Plan (SWPPP), the business does not
have to submit the forms to MDEQ but must retain the SCNOI and the SWPPP at the
business site. The business must be able to produce the forms upon demand by
MDEQ.

Construction General Permit

The Construction General Permit, also known as the Large Construction General Permit,
applies to the discharge of storm water from construction operations involving the
disturbance of five (5) acres or more of soils. The clearing, grading and/or excavation of
lands is included in this General Permit and the acreage amount includes the total land
area disturbed over the full length of the project. The Construction Notice of Intent
(CNOI) is the form used to apply for coverage under the State Wide General Permit. The
CNOI and Storm Water Pollution Prevention Plan must be submitted to the MDEQ at
least thirty (30) days prior to beginning construction activities. MDEQ staff will
review the submitted information, determine if the technical requirements for coverage
issuance have been met and make a decision regarding the issuance of the coverage. The
business can not begin the construction activity until they have received written
approval for their request from of MDEQ.

Baseline General Permit

The Baseline General Permit applies to the discharge of storm water associated with
certain industrial business operations not addressed by any other storm water discharge
permit but are subject to the applicable regulations. Industrial business operations

(chromated copper arsenate). The Wood Treater General Permit requires the testing of
storm water for certain chemical pollutants and sets a limit for those same chemical
pollutants. The Wood Treater Notice of Intent (WNOI) is the form used to apply for
coverage under the Wood Treater General Permit. The WNOI and Storm Water
Pollution Prevention Plan must be submitted at least sixty (60) days prior to beginning
treatment operations. Treatment operations cannot begin until the business has
received written approval from the MDEQ.

The previous discussions of the many types of general permit established by the MDEQ
is only a brief and broad description of the intent of the general permit discussed. On a
case-by-case basis, the MDEQ may determine that an individual permit may be more
protective of human health and the environment. If the MDEQ does make that
determination, the business must apply for an individual permit.
