Elinor Adensara, Chief Licensing Branch #4, DL FROM:
Ronald L. Ballard, Chief Environmental & Hydrologic Engineering Branch, DE s
SUBJECT:
INSPECTION OF BLACK FOX EROSION CONTROL PLAN'S EXEClfTI0l' On Neverber 10, 1983 Dr. Germain LaRoche inspected the results of the applicant's efforts to stabilize the Black Fox site as stated in their Erosion Control Plan submitted May 28, 1982. The results of this inspection are supplied as an attachment.
It is the Staff's conclusion that the applicant has perfomed an excell'ent job of establishing erosion control on the Black Fox site. The Staff does not foresee that any but nomal erosion sediments would be transported offsite provided that no unusual events occur to damage the described control l
measures.

INSPECTION OF BLACK FOX EROSION CONTROL PLAN'S EXECUTION On April 6,1982, Public Service of Oklahoma, applicants for the Black Fox Nuclear Power Station Units 1 and 2, filed a Motion for Termination of Proceeding and Withdrawal of Application, wherein they requested that the 4
Atomic Safety and Licensing Board enter an order termirating the instant proceeding and permitting -them to withdraw, without prejudice,- their - - - -
l application for construction permits.
1-On April 16, 1982, the Staff filed a response which suggested that the Board defer ruling until it received additional information from the applicants.
Board's Order of April 19, 1982 directed that applicants should file a document i,
describing the nature and extent of site preparation activities already under-taken and of the restorative measures, if any, proposed to be undertaken.
On May 14, 1982, applicants filed a response, among which it was stated "there
!r are no current plans either to dismantle any of the facilities or to redress any of the site features".
Applicants further requested that the Board grant i,
the -instant Motion, subject to the condition that applicants submit within a reasonable time after the end of 1982, a plan which addresses the need for site redress consistent with the future use detsmined for the site, and that said plan be subject to review and approval of the Staff.
On May 28, applicants 1
filed Dr. West's supplemental affidavit which described actions which would be taken to control erosion in the area of the inclined Reactor Pressure Vessel (RPV) haul road leading from the barge slip facility.
i On April 17, 1982, Dr. Gennain LaRoche, Senior Land Use Analyst in the 1
Envirormental & Hydrologic Engineering Branch, visited the Black Fox site to l
investigate the environmental impact thus far imposed onsite and to evaluate the potential environmental impact on and off site of abandoning construction
- of the nuclear power plant.
In a reply to the ASLB filed on June 2,1982, to which was attached an affidavit i
of Dr. Germain LaRoche the Staff recommended that "any conditions imposed upon i
withdrawal of the application should be specific, address anticipated adverse impacts from the site as it now exists, and be decided upon at temination and not left to the ' review and approval' of the Staff at some future date."
The Staff recommended that the Board grant the instant Motion, without prejudice, but subject to the following tems:
a)
The channels along the inclined RPV haul road and the slopes along i
both sides of the barge slip and of the inclined RPV haul road shall be stabilized to control erosion.
b)
Efforts shall be undertaken to ensure the long-tem stability of the soils in the eroded portions (1) of the engineered drainage system, (2) of the area surrounding the helicopter pad, and (3) of the areas al,ong the access roadway and railroad rights-of-way.

j On November 10, 1983, Dr. Germain LaRoche returned to the Black Fox site (BFS) and inspected the results of the applicant's efforts to stabilize the site as t
stated above.
He was accompanied by Public Service Company of Oklahoma personnel, Dr. John West, former Manager of BFS and now Manager of Fuels, Richard Mattes, present Manager of BFS, and_Desmond Nistetter, Managergl_ _ _
Scheduling and Cost Control, BFS.
Present Condition of the Site and Staff Evaluation The eroded channels along the inclined RPY haul road have been covered with concrete.
The bales of hay that were on the surface of the haul road itself have been replaced with rafiroad ties.
The slopes leading from original grade to the edge of the haul road have had topsoil added followed by hydroseeding of i
perennial grasses.
On the steeper portion of the slope chicken wire was placed over the hydroseeded material. An irrigation system was installed and water was applied as needed.during the past summer.
Irrigation will continue next
- y stanner.,
The perennial grasses are well established with no erosion observed. With i
another growing season with irrigation, a permanent grass cover, that will prevent all but normal erosion, will be established. The conreted channels a
i cannot erode and the railroad ties will not deteriorate as the bales of hay I
were doing.
I The engineered, drainage system has stabilized and continues to drain into a
- ettling pond.
Therefore, whatever small quantities of sediment that results from normal erosion rate are not transported offsite but are deposited in the 2
settling pond.
The area surrounding the helicopter pad was treated in the same way as the i
{
slopes of the haul road except that watering was carried out by means of a tank truck.
Where the main portion of the runoff from the heliport and adjacent parking lot flows over this slope a concrete spillway was built.
Grasses probably could not prevent erosion in this area but the spillway certainly will.
The grasses on this slope are well established.
The areas along the access roadway and railroad rights-of-way were graded where necessary to reduce slopes and thus reduce erosion potential.
A point was made that the last pass of the bulldozer on the slopes re.; ult in the tracks i
in the soil being horizontal and not vertical to the slope.
This results in little dams rather than channels in the soil thus reducing the potential for erosion.
These areas were also hydroseeded and watered as necessary.
It was noted at the November site visit that these areas are now well covered with perennial grasses.
I Photographs of the above areas were taken in 1982, during repair work in the spring of 1983 and on November 10, 1983.
These photographs will be retained 1
in the EHEB file on Black Fox until action on the application is completed.

t t,
In addition to the erosion control that has now been implemented, the Licensing Board Order dated January 7,1983, specified that if a decision to build at the Black Fox site was made applicants were to advise the Licensing Board whether each facility and other improvement made at the site under the amended LWA would be utilized in the alternative project design.
On November 26, 1982, Public Service Company of Oklahoma publicly announced plans for the construction of Inola Station, a coal-fired electric power-generating station, to be built at the site of the cancelled Black Fox Station l
nuclear project.
In the applicants' resnonse to the Board dated January 23, 1983, applicants stated that they will dismantle any unnecessary Black Fox improvements and will return disturbed areas to conditions consistent with the present use of the site.
Because the eros' ion control measures recommended by the staff have been executed in an acceptable way and because the decision to construct and operate Jnola Station coupled with the mechanisms for redress described in the apsificants' response to the Board dated January 23, 1983, appear to provide adequate assurance and information concerning the future use and environmental control of the Black Fox site, the staff recommends that the i
Board grant the Motion for the Ternination of Proceeding and Withdrawal of l
Application for Construction of the Black Fox Nuclear Station.
