s*ummer Nuclear Station South Carolina Electric & Gas Company hereby submits a copy of National Pollutant Discharge Elimination System Permit No. SC0030856.

The South Carolina Department of Health and Environmental Control has made a minor modification to the permit to remove all references to Outfall 013. This outfall now ,has coverage under the NPDES General Permit for Storm Water Discharges Associated with Industrial Activity. The permit modification date was issued on March 8, 2016, with an effective date of April 1, 2016. This permit ensures that all discharges from the plant to Monticello Reservoir and Broad River meet the Federal and State guidelines.

If there are any questions, please contact Ms. Susan B. Reese at (803) 345-4591.

A. The "Act", or CWA, shal~ refer to the Clean Water A.ct (Formerly refe11:ed to as tlie Federal Water Pollution Control Act) Public Law 92-500, as amen_ded. *

B. The *;average" _or "arithmetic mean" of any set of values is the summation of the indivic;lua.l values divided py the number of individual v~lues. *

C, "Basin" (or "Lagoon") means any in-grbtmd or earthen structure designeq t~ receive, treat, store, temporarily retain and(or allow for the infiltratfon/evaporation of-wastewater.

D. ")3lowdown'~ *means the minimum discharge of recirculating w~ter for the purpose of discharging materials cmitained. in the water, the further buildup of which would cause conce11trafion in amounts exceeding limits

established by pest engineering pr~ctices.

E. * "Bottom ash" means tpe ash that drops out ofthe funiace gas stream in the furnace and in the economiz~r sections.

Economizer ash 1s included when it is collected with bottom ash (40 CPR 423.11 (f)).

G. "Chemical metal-cleaning waste" means any wastewater resulting from the cleaning ofany metal process equipment with chemical compoUnds, including, but not limite_d to, boiler tube cleaning (40 *cFR 423 .11 (c)) ..

H. "Coal pile runoff" means the i*ainfall runqfffrom or through any coal storage pile (40 C:fR 423.ll(m)).

I. A "composite . sample" shall be defined as one of the following four types:

I. An influe~t or effluent portion collected continu~msly over a specified period of time at a rate prop9rtional to the flow. * * *

2. *A comhinatfon of not less µia:n 8 in.fluent or .effluent gral? samples collected at regular (equal) intervals over a specified period of time alid composited by increasing the volume of each aliquot in proportion to flow. If continUOl}S flow measurement is i;lot USed to composite in ptOportion to flow, the following tnethoq Will be used: An illstarttaneous flow 111eastirement should be taken eac~ tirp.e a grab sample is collected. At the end of the samp~ing period, the instantaneous flow. measurements should be summed to obtain a total flow. The instantaneous flow measurement can then be divided by the total flow to determine the percentage of eac~ grab s~ple tQ be combined. T}lese combined samples fotm the composite sfilll,ple. *

3. Acombinatio~ of not l.ess than 8 influent or effluent gtab-sa111ples of equal volume but at variable time intervals to that are invei~elyproportional thevoltu~e of the flow. In other words, thetimeintetyal betweena,liqlJots is reduced as the volume of flow increases. * *

4. If the effluent flow varies by less than 15 percent, I:!- combination of not less th&n 8 influent or effluent grab samples of const~nt (equal) volume collected at regulai* (equal) time interv1,1ls over a specified period oftime.

precipitators, electrostatic precipitators, and/or fabric filters ..Economizer ash is included when it is collected with fly asl.1 (40 CFR 423.11(~)).

0. The "geometric mean" of any s~t of values is the Nth root of the proquct of the individual values where N is equal to the number of individµa1 values, The geometric mean is equivalent to the antilog of the arithmetic mean of the logarithms of the individual values.

The tpanual shall contain operation and maintenance instructions for all equipment and appurtenances..

associated with the waste treatment facilities and land application system, if applicable. The manual shall contain ageneral description ofthe treatment process(es), the operational pro9edures to meet the requirements of E.1 above, and the corrective action to -be taken should operating difficulties be encountered.

4. The permittee shall provide for the performance of daily treatment facility inspections by a certified <;>perator of*

the appropdate gra~e as defined in Part v:E of this permit. The Department may make exceptions to the daily operator requirement in accordance with R.61-9 .122.41 (e)(3)(ii). The inspections shall include, hit should not necessarily be limited io, areas whi~h require visual observation to determine efifoient operation and for which immediate corrective measures can be taken using the 0 & M manu~ as a guide. {\.11 inspections shall be recorded and shall include the date, time, and name of the person maltjng the inspection, corrective m¢asures taken, and routine equipment mairttenartce, repair, or replacement performed.

For new facilities, this roster must be submitt~d prior to placing the fa~ility into operation. Additionally, any changes in operator or operators

{including their certification grades)_ shall be submitted to the Department as they occur.

6. Wastewater Sewer Systems

a. Purpose. This section establishes rules for governing the operation and maintenance of wastewater sewer systems, including gravity or pressure interceptor sewers.

Part II Page 17 of37 Permit No. SC0030856 M. Bypass l

Bypass not exceeding limitations. The permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded but only if it also is for essential maintenance to assure efficient operation. These bypasses are not stibject to th~ provisions of Part II.M.2 and 3 of this section.

2. *Notice.

a. Anticipated bypass. Ifthe pennittee knows in advance of the need for a bypass, it shall submit prior notice, if possible, at least ten days before the date of the bypass to the DHEC/Bureau of Water/ Water Facilities Permitting Division. * *

b. Unanticipated bwass. The permittee shall submit notice of an unanticipated byp~ss as required in Pait II.L.5 of this section. ,

3. Prohibition of bypass

a. Bypass is prohibited, and the Department may take enforcement action against a permittee for bypass, unless:

(1) ~ypa.Ss was unavoidable to prevent loss oflife, personal injury, or severe property damage; (2) There were no feasible alternatives to the bypass, such as the .use of auxiliary treatment facilities,

rete~tion ofootreated wastes, or maintenance during normal'periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been instaUed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during t10rmal periods of equipll1ent downtime or preventive maintenance; and (3) The permittee submitted notices~ required under Part II.M.2 of this section.

b. The Department may approve an anticipated bypass, after considering its adverse effects, ifthe Department determines th~t it will meet the three conditions listed above in Part II.M.3.a of this section.

N. Upset

1. Effect of an upset. An upset coµstitutes an affirmative defense to an action brought for noncompliance with such technology based permit effluent limitations if the requirements of Part II.N .2 of this seetion are met. No determination made during administrative ~eview of clauns that noncompliance was. caused by upset, and befor~

an action for noncompliance, is final administrative action subject to judicial review.

2. Conditions necessary for a demonstration of upset. A pennittee who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporai10ous 0perating logs, or other relevant evidence that:

a. An upset occurred and that the permittee can identify the cause(s) of the ups~t;

b. The,permitte4 facility was at the time being Pr<?perly operated; and

c. The permittee submitted notice of the upset as required*in Pait II.L.5.b(2) of this section.

d. The permittee compli~d with any remedial measures req4iredunder Part II.D of this section.

3. Burden of proof. In any enforcement proceeding, the pennittee seeking to establish the occurrence of an upset

.has the burden of proof. .
