Dear Mr. Muntzing:
Thic ic in reply to Mr. DcYoung's letter of October 19, 1970, requecting our cocenents on the cpplication by the Arkancan Pcwcr and Light Cc:cpany for a construction permit for the propoced Arkancan 1:uclear One, Unit 2, Pope County, Arkencas, AEC Dochet no. 50-368.
F.'c have revicted the Prelin.inary Gt.fcty Analycis Ecport and its tecndment through 1.'o. 13,.
the applicant's environ;.mntal r : port dated September 10, 1970, and other materials provided by cubsequent letterc.
'lhe co=ents of the Mid-Atlantic Coactal Firhcrie: Eccecreh Center, L."FS, Depcrtment of Cc:mnerce were obtained and c.rc included as part of this revicu.
Unit 2 uill have an electrical eutput of 950 megawatts and will be cen-structed adjtcent to Unit 1 on the 1100-acre project cite. Cooling cnd dilution water ut the rm.e of cbcut 1700 cfc vill be pur. ped frca DErdanelle Reservoir, pauscd thrcuch the condencer where it will be heated 150 p, and returned to the reservoir. The int d.e structure contains trach racks and traveling ccreens. ' Unit 2 will use a cloccd-cycle cooling system
$ncorporating c cooling touer (type unspecified) to cool the effluent from the condenser. A maxi:.u:a of ho cfc of makeup water will be punped from the reservoir. About 27 cfc of this water will be evaporated from the cooling tower end 13 cfc will be returned to the reservoir.
The temperature rice of thic diccharge is undetermined. Unit 2 will share the intake and discharge structure: of Unit 1.
Former Cc:miccioner pautzke's letter of May 29,1%8, to your Cc:rnission, on the constructica permit for Unit 1 discusced the fish and wildlife recources in the project area, the effect the project would have en them, and recc: mended measures to protect these recources from cignificant damage.
The Department's letter dated March 10, 1971, cc:n.enting on the draft enviror. mental statement for Unit 2, discucced neveral problem areas in the statement that needed clcboration. Thcy related to the effects of Unit 2 by itcelf and the combined effects of both units on fish and wild-life 'recource and the environ:aent.

4 We still are concerned that a delicate thennal balance may exist in Dardanelle Recorvoir and that operation of the two units of the proj-
~~
- cet may result'in significant thermal strenc and danage to aquatic life. ' Also, we ere concernca that the chlorine used for algae and fungus control end the sulfuric acid, enuctic soda, phosphates, and other conpounds uced for scale und corro:icn may damac,e nouatic life; that a significent number of fish eny becomo entrained cud destroyed in the intake cystem, or beco:nc trapped and ctie on the intake screens; that ~ construction of project transmiccion linen uny have on adver c impact on fish and ui3dlife resources and the environnent; and that the radionuclide bui.1 dup in the receiving waters with both unit operating nay affect fich and vildlife resources adversely.
The preoperatienol radiological monitoring program for Unit 2 lacks
+
many details. However, the ongoing nonitoring program for Unit 1 is more complete and chculd enco.nacs the coincions from Unit 2.
The radiological nonitoring progrera for the entire project would provide for adequate surveillance and protection of the fish cnd vildlife resources ar.d the environnent if the recc.Taendations set forth in our letter of L:cy 29, 1963, en Unit 1 are folloued.
The project hos the potential of inflicting significant adverse impact on the environment of the area. However, we believe that by exercia-
- ing care in the design and operatien of the ecndenser cooling water
. cystem and with the use of adequate radiological and errrironmental monitoring prograns, najor difficultics can be avoided. Therefore, we vould have no cbjection to the issuance of the construction permit.
The applicant has exprenned assurance of full cooperation with the Bureau of Sport Fichcrica and Uildlife, other Federal egencies, and State and local authoritics in acycloping and carrying out a program for the protection of fish and, wildlife resources and the environment.
In vicu of the importance of the fish and wildlife resources of the project area, we recommend that the Arkansas Power and Light Company:
1.
Continue the preoperational radiological and environmental curveys ' currently being conducted for Unit 1 vith necessary expansion of the curveys to enconpass the added effects of
' Unit 2.
~
- 2.. Continue to prepare reports of these surveys and provide nix copics of each to the Director of the Bureau of Sport Fisheries -and Wildlife, for evaluation p'rior to operation of Unit 1.

Moot uith the above-named agencies at frequent intervals to discuss any new or modified plann and the progress of the ecological and radiological curveya.
4 Follouing startup of Unit 1, conduct postoperational en-vironn.ents1 and r::diologien1 surveys follo. ing planc developed in cooperation with the Bureau of Oport Ficherica and Wildlife
/
and other Federal end State agencies, anc2 ze the data, and 7
preparc and cubmit repods annually until it -has been demon-strated conclusively thit no significant adverse conditions exist.
5.
Further studies be conducted to determine the need for in-stalling coditional facilitics to cool the effluent from both units of the project to.a temperature that vill not cauce signi-L fiennt de an3e to fish and other aquntic life in Dardanelle Eccervoir.
Such fa::ilitica chall be incorporated in the project that the studies dc:aonstrate are needed.
Additional cooling towers, cooling ponds, pct.er spr.ay mcduloc, or combination of these or other fncilitier should be nt1]y considered cs alter-natives'for the one' chrong;3 cooling system design for Unit 1.
6.
Studies he made to determine the effectiveness of the traveling screens at the intG.c structure to prevent cinnificant loss of fich and other nquatic orcanicm3 by entrapment or en-
. train::;cnt in the coolin~, unter system.
If the need is demon-strated, project ::.edifications including decrcasing intake approach velocities or ccnctructing a bypass for trapped fich may be re-quired and must be fully considered.
7.
The impact of project transmiscien line construction and maintenance on the fi'sh and wildlife renources and the environ-ment be minimized to the entent posnible by following the guide-lines in the publication entitled, " Environmental Criteria for Electric Transmicsion Lines" published February 10,1970, by the Departmente of Interior end Agriculture.
I 8.
Additional facilitics to reduce or climinate discharging chemicals or relat.ed hornntl compounds to Dardanelle Reservoir to protect aquatic life frca toxic cffcets be incorporated in the project. Mec!r.nical ncnns of controlling biological growth, scale, and other_ harmful or obstructing deposit should be con-sidered. No chlorine shall be released to the envirorenent.
Facilitics to return all chlorine to the atrocphere, such as evaporctinc ponds, recirculating the chlorino effluent through the cooling to:cr, cnd cther modifict.tionc or project ctructures and operations moy be required and mutt be fully considered.
