State Narrative Language For: Antidegradation
It is the policy of the Environiental flanagement Commission to lain tain, protect, and enhance mater quality
nthin the State of North Carolina. Pursuant to this policy, the Environmental Hanagement Commission nil not
approve any project or development nhich would result in the significant degradation of waters whose existing
quality is better than the assigned nater quality standards, unless such degradation is found by the coimiss-
ion to be justifiaBle to provide necessary economic ind social development. In such cases, those pollution r
control leasures necessary to aaintain high iater quality"nil be required where physically and economically
feasible. Prior to approval of; my project or deveiopient which nil result in the significant degradation of
»ater quality, the commission nil solicit, through public notice or public hearing or both, comments from the ,
public and intergovernmental agencies relative to.the project or development and anticipated water quality
degradation. In"cases.where the project or development, requires a HPDES penit, the Environmental Hanagement
'Commission shall publish in conjunction nth the public notices required by 15 HCAC 2H .0109U) (regarding
application for NPDES penit] and 15 NCAC.2H .0109(b) (regarding a public hearing on MPDE3 .perilt application)

iore, the commission shall considsr the present wd inticioated usage of said wter, including any. uses not •
specified by the assigned classification (such as outstanding national resource wters or »aters.of exceot-
ional-Mter. quality)'and nil not'allo» degradation'of hign quality «aters belon the »ater-.quality-necessary

atively demonstrated to be non-bioaccumulative) »hen not specified elswhere in this Section, shall not exceed
the concentration specified by the fraction of the 96-hour LC50 value »hich predicts a no effect chronic level
• (as determined by the use of, established acute/chronic ratios). If an acceptable acute/chronic ratio is not
available, then that toxic substance shall not exceed one-one hundredth (0.01) of the 96-hour LCSO or if it is
affirmatively demonstrated that a toxic substance has a half-life of less than 96 hours or is not bioaccumu-
.lative, the maximum concentration shall.not exceed one-txentieth (0.05] of the 96-hour LCSO. If it is
affirmatively demonstrated that the standard for a particular toxic substance as specified in Rule .0211 or
.0212 of this Section'is inappropriate for a specific stream segment, the commission lay revise the applicable
standard on a case-by-case basis in accordance nth the provisions of Section 143-T214.1 of the Seneral

State Narrative Language Pars Low Flow
The governing flow criterion for water quality standards except toxic substances, generally shall be the
unnui average flow for a period of seven consecutive days tint has an average recurrence of once in
10 years (7810).
These governing criteria are established specifically for setting effluent Imitations jnd for the design of
mstiwater treatient facilities. In addition, the governing flow also establishes a value below whicn
deviations froi water quality standards can be anticipated.
State Narrative Language For: Mixing Zones
A imng zone lay be established in the area of i discharge in order to provide reasonable opportunity for tne
nxture af the wastewater with the receiving waters. The liiits of such lixing zones will be defined by the
division on a case-by-case basis after consideration of the lagnitude and character of the waste discharge and
