Section 303(d) Federal Clean Water Act (1972)
Requires states to submit list of sites not meeting state water quality standards to EPA every two years
Requires states to develop a Total Maximum Daily Load (“TMDL”) for each pollutant causing impairment
If states don’t develop list or TMDLs, EPA must do it !
No sites with acute No sites with acute impacts on 303(d) listimpacts on 303(d) list
Acute impacts to water Acute impacts to water quality dealt with quality dealt with immediatelyimmediately
List includesList includes persistent persistent impairments identified impairments identified through water quality through water quality monitoringmonitoring
Determining Impairment
In other words…
Listing is based on results of measurements and sampling performed by DHEC or other acceptable sources.
What is a TMDL ?
Total Maximum Daily Load Maximum amount of a pollutant
that a waterbody can receive from all sources, and still meet water quality standards
Maximum allowable amounts of point and nonpoint source contributions, plus a margin of safety
Identify suitable approach, based on Pollutant(s) of concern Available data Watershed size, characteristics EPA’s approval
Characterize existing pollutant loads Determine percent reduction
from each source so that instreamwater quality standards are met
TMDL Development Process
TMDL Facts
• TMDL process includes public notice, comment period
• All TMDLs must be approved by EPA
• Final TMDL confers no additional regulatory authority to DHEC• TMDL implementation through
existing regulatory and non-regulatory mechanisms
TMDLs in South Carolina 312 Approved TMDLs
51 TMDLs being implemented 17 primarily point sources 34 primarily nonpoint sources
0 TMDLs on public notice 47 TMDL drafts completed 25 TMDLs under development
(Unsolicited Advice)
Become familiar with 303(d) list TMDLs will be developed for
these waters (unless WQ improves!)
If a TMDL has already beendeveloped for your watershed Apply for a grant to implement
voluntary portion If no TMDL has been developed
Develop it in cooperation w/DHEC & EPA
