WPPSS 3, 5 LWA A.

Site Location The proposed site is located in southeastern Grays Harbor County, Washington,-

one mile southeast of the confluence of the Satsop and Chehalis Rivers.

The proposed site is 16 miles east of Aberdeen, Washington, and'26 miles west-southwest of Olympia, Washington.

B.

Site Description and Exclusion Area Control The site consists of 2450 acres the largest part of which is located od a ridge above the Chehalis River. The planned location of the plant stiructures is at an elevation of 390 feet above MSL.

The exclusion area is approximately circular in shape with a minimum bound-ary distance of 4,300 feet (1,310 meters). The applicant will own only part of the exclusion area and will obtain the authority to determine all activities within the balance of the exclusion area by entering into agree-ments with the land owners and through the granting of appropriate easements on these non-owned properties which will convey to the applicant the authority to control access. The only activities unrelated to plant operation on the non-owned properties within the exclusion area will be timber farming activities, and these activities will be controlled through the use of easements.

The applicant presently owns about 272 acres (not all of which is within the exclusion area) and is negotiating to purchase approximately 796 acres within the exclusion area which are presently owned by private corporations.

I

. It is the applicant's intent to purchase the mineral rights on all lands to be acquired in fee. The applicant expects all land purchases to be completed by July,1975. We will require that the portion of the exclusion area required for plant construction, which is included in the por-tion the applicant intends to own, must be acquired by the applicant before an LWA can be issued.

The property within the exclusion area which will not be owned by the ap; icant is approximately 1070 acres in size and is owned by individuals or private corporations with the exception of a 16 acre tract which is owned by the State of Washington. These lands are all commercial tree farms. The easements to be obtained by the applicant on these non-owned lands will specify that the applicant will be notified in advance of the commencement of any activity which is undertaken in these areas and in advance of any entry on these lands by the owner, his agents or employees.

In addition, no buildings or residences of any kind may be constructed in these areas other than temporary structures and facilities as may be necessary for timber farming operations. Plans and specifications for construction of any such temporary buildings will be submitted to the applicant for review and approval. The' mineral rights for the non-

l owned lands will not be acquired by the applicant, however, the easements will include control over mineral rights and will specifically exclude mineral exploration and mining activities. The applicant expects all negotiations concerning the agreements and easements on the non-owned lands within the exclusion area to be completed by July,1975.

. We conclude that the authority granted to the applicant through the agreements and easements entered into with the property owners of the land within the exclusion area which the applicant will not own can comply with the requirements of 10 CFR Part 100. However, before giving a final opinion on this matter, we will require that the applicant produce for our review the executed agreements granting the easements, of produce persuasive evidence such as letters of intent with the property owners including the State of Washington, to demonstrate reasonable assurance that the applicant will have the proper authority regarding activities within the exclusion area.

The exclusion area will not be traversed by any public waterways or railroads. A Grays Harbor County road, an extension of Keyes Road, will provide vehicular access to the exclusion area. A Bonneville Power Administration transmission corridor also crosses the exclusion area. The l

applicant has initiated discussions with the County and BPA to obtain the authority to control access to the exclusion area on these routes and anticipates that final agreements will be made prior to l

August 1, 1975.

4 C. Population and Population Distribution The proposed site is located in~ a rural area with low population.

The present and projected resident populations in the area surrounding the site are shown in Table 2.1.

TABLE 2.1 Present and Projected Population

Radius, Miles 1970 1980 2020 0-10 9,733 10,~451 13,469 0-30 124,557 141,275 219,785 0-50 345,941 391.475 601.690 The 1970 population density within ten miles of the site was 31 persons per square mile, and within 30 miles of the site was 44 persons per square mile. The population densities are anticipated to increase only slightly by 1980, near the time of the comnercial operation of the first unit of the proposed plant. By 2020, the population density is projected to be 43 persons per square mile within 10 miles of the site and 78 persons per square mile within 30 miles.

Grays Harbor County attracts a number of daily and seasonal transients primarily during the suniner months. The majority of these transients are visitors to the Pacific Coast area of the county some 30 miles west of the site and to other parks and recreational areas. The closest parks to the site are two relatively small parks with limited facilities located between 7 and 10 miles from

4 I

. the site. We conclude that the seasonal transients do not significantly altar the population distribution within at least 10 miles of the site.

The applicant has selected a low population zone with an outer radius of 3 miles. The total 1970 resident population within the low population zone was 260 persons, the majority of which resided in the Chehalis River Valley. There are no significant transient populations within the. low population zone other than travelers through the area (principally on U. S. Highway 12). As a result of our evaluation of the low population zone proposed by the applicant for the WPPSS 3, 5 site, we conclude that there is reasonable assurance that the 10 CFR Part 100 definition of the low population zone can be satisfied in that no unuaual features have been identified which would prevent the development of adequate emergency measures regarding the evacuability of the low population zone.

The nearest population center, as defined in 10 CFR Part 100, is the Aberdeen Hoquiam urban area which contained a 1970 population of 28,549 persons. The population in the Aberdeen-Hoquiam area begins at a point approximately 15 miles west of the site and the nearest politicial boundary for this area is approximately 13 miles from the plant site. This distance satisfactorily meets the 10 CFR Part 100 requirement that the population center distance be more than one-and-one-third times the low population zone distance.

We conclude that the specified minimum exclusion distance (1,310 meters) and low population zone radius (4,830 meters) are of sufficient size in

s u

,t.

)

. comparison with previously licensed plants that there is reasonable assurance that adequate engineered safety features can be provided to 5

I satisfy the exposure guidelines of 10 CFR Part 100 for reactors of the general type and size proposed for the WPPG 3, 5 site.

. D. Nearby Industrial, Transportation, and Military Facilities there is little industrial activity in the vicinity of the proposed site.

One small manufacturing facility employing 10 persons is located 4.8 miles northwest of the site. The applicant states that there are plans to construct a chemical plant 4.7 miles east-northeast of-the site.

This facility will employ about 50 people and the main product will be bleaching chemicals for the pulp industry. A quantity of 1 methanol and nitrogen gas will Ipe stored at the chemical plant but, because of their distance from the site, these materials will present no hazard to the proposed nuclear plant.

U. S. Highway 12, the major highway in the vicinity of the site, is a four lane divided highway which passes in an east-west direction through the Chehalis Valley about 3 miles north of the site.

A single track railroad line, maintained by the Union Pacific Railroad, i

l l

runs along the south bank of the Chehalis River approximately one l

mile north of the proposed location of the plant structures (and about l

l 350 feet lower in elevation). A main line of the Northern Pacific l

Railroad runs through the Chehalis Valley about three miles north of the l

site. The average daily rail traffic on the Union Pacific line is conprised of two freight trains carrying mainly lumber and related products. Some l

hazardous materials are shipped on this line and consist primarily of j

caustic soda, chlorine, and propane. It is also projected that about one tank car of methanol will be shipped on the railroad every three l

l l

,e.

.a l

. to four months when the new chemical plant east-northeast of the site is in operation. The applicant has evaluated postulated accidents on the railroad one mile north of the site including an explosion, formation of a flammable vapor cloud, and a chlorine release. We have reviewed the analyses and conclude that the consequences of these railroad accide".ts are such that ti.e plant could be designed to withstand them if necessary.

The Chehalis River flows in a westerly direction in the valley about one mile north of the site. The river.is used by small pleasure and fishing craft and is not utilized for commercial barge transportation in the vicinity of the site.

4 Elma Municipal Airport is located approximately two miles northeast of the site. The airport has a single turf runway 2,000 feet in length and is used by light private aircraft. It is estimated that at present i

there are approximately 1,825 operations per year. The applicant states that expansion of the airport is currently under study and, depending on the results of the study and availability of resources, there

are plans te pave the runway and extend it to approximately 3,500 feet.

With the proposed improvements the airport will be capable of handling aircraft up to 12,500 pounds gross weight. The applicant cites a Washing-ton State planning document which projects a growth to approximately f

4,000 operations per year for the Elma airport. The Tederal Aviation Administration *s national airport system plan, published in 1972, projects 7,000 operations per year at Elma in 10 years, all of which will be aircraft under 12,500 pounds.

The nearest airport with commercial scheduled flights is Bowerman Airport located in Hoquiam about 22 miles west of the site. An airway between Olympia and Hoquiam passes near the site area and there are currently 12 scheduled flights per day between these cities by single engine and light twin-engine aircraft at altitudes between 5,000 and 10,000 feet. This airway is also routinely used for training flights by the l

U. S. Army from Fort Lewis, Washington, flying single and twin-engine aircraft and helicopters. The applicant has obtained estimates of the military traffic which indicate that the maximum number of such flights is 15 to 20 per day with the average estimated to be approximately 12 to 15 per month.

.

• On the basis of previous analyses of aircraft activity at other nuclear power plant sites, we conclude that the type and number of aircraf t ut131 ming the aviation facilities in the vicinity of the proposed site is such that the plant could be designed to withstand the impact of such aircraft if required.

w The applicant states that there are no military facilities or pipe' lines in the vicinity of the site. The area around the plant will be cleared to provide a minimum distance of 300 feet from the safety related structures to protect the plant against forest fires.

4 On the basis of our review of the industrial, transportation, and military activities in the vicinity of the proposed WPPSS 3,5 site, we conclude that there are no nearby activities which would preclude site acceptability, and that the WPPSS 3,5 site is suitable for reactors of

' the general type and size proposed.
