GG ER QUESTION 340.11 Provide the maximum, minimum and average calculated (3.6) levels of total and free residual chlorine at the discharge, prior to mixing with the Mississippi River, during and after periods of circulating water chlorination.

RESPONSE

Total residual and free available chlorine in the effluent discharge of power plants is regulated by the National Pollutant Discharge Elimination System (NPDES). A NPDES permit for the Grand Gulf Nuclear Station has been issued in accordance with the provisions of the Mississippi Air and Water Pollution Control Law (Section 49-17-1 et. seq., Mississippi Code of 1972), and the regulations and standards adopted and promulgated thereunder, and under authority granted pursuant to Section 402(b) of the Federal Water Pollution Control Act. The free available chlorine concentration limitations of the NPDES permit are an average concentration of 0.2 mg/l and an instantaneous maximum concentration of 0.5 mg/1. Further limitations on chlorine discharge by the NPDES permit are also required. The permit states, "Neither free available chlorine nor total residual chlorine may be discharged from any unit for more than two hours in any one day and not more than one unit may discharge free available or total residual chlorine at any one time. The exact time of discharge of free available or total residual chlorine shall be recorded for each unit and reported as required."

The Environmental Protection Agency (EPA) is actively involved in

! developing means to reduce chlorine discharge. As part of this nationwide program, the GGNS NPDES permit requires a chlorine minimization report study plan to be submitted 90 days prior to Unit 1 fuel loading. The minimization report is to be submitted 15 months after startup of Unit 1 and Unit 2. This study shall evaluate practicable methods to reduce total residual chlorine levels, including but not limited to 1) minimization of chlorine addition commensurate with control requirements, and

2) discontinuation of blowdown during chlorination and subsequent periods of high concentration.

QUESTION V'

340.14 Provide copies of correspondence between MP&L Co. and (5.5) the State of Mississippi Natural Heritage Program documenting their review of the site and the four new transmission line right-of-ways associated with the construction of the Grand Gulf Nuclear Station.

RESPONSE

The Mississippi Natural Heritage Program was established by the Mississippi Bureau of Outdoor Recreation, the Wildlife Heritage Committee, and the Nature Conservancy in 1976. The Mississippi Natural Heritage program was established to identify significant natural areas and to recommend means of protecting these areas.

Information on ecologically sensitive areas in Mississippi can be obtained from the statewide inventory the Natural Heritage Program has been compiling since its establishment in 1976.

Review of the Grand Gulf Nuclear Station site and the four new transmission line right-of-ways by the Mississippi Natural Heritage Program prior to construction was not possible since the

(}

s_-

program did not exist until 1976. However, a review was conducted by the appropriate state agency, the Mississippi Game and Fish Commission, as documented in the Construction Final Environmental Statement.

However, in 1977 MP&L consulted with the Mississippi Natural Heritage Program for information on ecologically sensitive areas near the GGNS site. As part of this consultation, MP&L provided the Mississippi Natural Heritage Program with pertinent sections of the GGNS Environmental Field Measurements Program Final Report. Computer printouts of special animal and plant species were obtained from the Mississippi Natural Heritage: Program in 1977 and were reviewed.

In 1978 the Mississippi legislature organized the Mississippi Natural Heritage Program as a department in the Mississippi Game and Fish Commission State Agency. Personal communications with Mr. John Burris and Mr. Joseph Jacob of the Mississippi Natural

-Heritage Program were conducted in regard to the GGNS trans-mission coridors. The Mississippi Natural Heritage Program had no recorded sitings or collections of rare, threatened,

~

endangered, or special concern plant or animal species along the GGNS transmission corridors.

RESPONSE

Maintenance and monitoring of the transmission lines will be conducted by personnel from the Engineering, System Operation, and Construction Department of Mississippi Power & Light Company.

Engineering, System Operation, and Construction is responsible for transmission line inspections. These inspections are conducted by aerial surveys and walking patrols at periodic intervals. These inspections include monitoring for erosion, structural damage caused by wind, vehicular damage caused by right-of-way encroachment by hunters and loggers, shrub growth and broken insulators. Problem areas are identified by the aerial surveys, and walking patrols to the problem areas clarify the extent of the problem to be corrected.

q_j QUESTION 350.14 When completed, provide a copy of the ongoing study (2.6) related to possible future disposition of the Callendar House located on the site.

RESPONSE

The Callendar House is an antebellum farmhouse which is in rather poor condition. In June 1973, Mr. James H. Stone, Assistant Administrator, Division of Historic Sites and Archaeology, Mississippi Department of Archives and History, discussed the official position of the state department in regards to the Callendar House in a letter to Ms. Myra Harrison, Acting Compliance Officer, Advisory Council on Historic Preservation.

This letter was in response to comments made by Ms. Myra Harrison on the GGNS Construction Draft Environmental Statement. Mr.

Stone of the Mississippi Department of Archives and History stated that the house had little historic or architectural significance and that the department did not intend to nominate it to The National Register of Historic Places. He further O'statedthatMP&Lshouldbeallowedtomakedecisionsregarding the future of the Callendar House.

A copy of this letter has been provided to the NRC as acknowledged in Question 350.15.

MP&L has not decided the future disposition sf the Callendar House. The Callendar House has nor been occupied for several years due to its uninhabitable condi'_1on. At the present time, the house is boarded and locked for safety and security reasons.

As part of the decision process in regards to the disposition of the callendar House, MP&L will consider several options for the house such as a visitor's display center, conference facilities, and demolition.
