This p l an has been developed t o e s t a b l i s h t h e o b j e c t i v e s and set f o r t h t h e procedures and gu ide l ines f o r t h e r e s t o r a t i o n of t h e P ro jec t Gasbuggy s i t e , which w a s t h e l o c a t i o n of t h e f i r s t U.S. underground nuclear experi- ment f o r t h e s t imu la t ion of low-productivity n a t u r a l gas r e s e r v o i r s . The gene ra l o b j e c t i v e s of t h e s i t e r e s t o r a t i o n p r o j e c t are t o plug and abandon a l l p ro jec t - r e l a t ed bore holes , remove su r face f a c i l i t i e s , and r e t u r n t h e s i t e t o i t s p r e t e s t s t a t u s , Deta i led ob jec t ives , s p e c i f i c procedures, and gu ide l ines which w i l l be followed during f i e l d a c t i v i t i e s are descr ibed he re in .

Background

I n 1958, t h e E l Paso Natura l G a s Company (EPNG) expressed interest i n t h e s t i m u l a t i o n of gas r e s e r v o i r s wi th nuc lear explos ives , of such a procedure w a s presented i n a f e a s i b i l i t y s tudy which w a s completed i n 1965. The s tudy w a s a j o i n t e f f o r t undertaken by EPNG, t h e U.S. Atomic Energy Commission (AEC) (now p a r t of t h e Department of Energy), and t h e Department of I n t e r i o r ' s Bureau of Mines, with t echn ica l a s s i s t a n c e from t h e Lawrence Radiat ion Laboratory (LRL) (now Lawrence Livermore Laboratory) . The s tudy, t i t l e d P r o j e c t Gasbuggy, descr ibed t h e nuc lear s t i m u l a t i o n of a gas r e s e r v o i r i n t h e P ic tu red C l i f f s sandstone formation i n t h e San Juan Basin of northwestern New llexico approximately 75 m i l e s east of Farmington (Figure 1).

The p r a c t i c a b i l i t y

EPNG subsequent ly proposed t o t h e AEC t h a t P r o j e c t Gasbuggy be conducted as a j o i n t Government-industry venture . The AEC concluded t h a t Gasbuggy would be a va luab le t echn ica l experiment and, toge ther with t h e Department of the I n t e r i o r , signed a c o n t r a c t w i t h EPNG on January 31, 1967.

D r i l l i n g t o assess t h e p o t e n t i a l of t h e s i t e began i n e a r l y 1967. Upon completion of two explora tory w e l l s , GB-1 and GB-2, t h e New Mexico San Juan Basin s i t e w a s accepted and i n June 1967, d r i l l i n g of t h e nuc lear emplacement hole , GB-E, w a s s t a r t e d . 'On December 10, 1967, a 29-kiloton nuc lea r explos ive w a s detonated a t a depth of approximately 4,240 f e e t i n t h e low-permeability P ic tured C l i f f s sandstone formation.

Af te r r e e n t r y d r i l l i n g , s i x major product ion tests were conducted. Two took p l ace i n 1968, t h r e e i n 1969, and t h e l a s t i n 1973. A t o t a l of approximately 400 m i l l i o n cubic f e e t (MMCF) of gas w a s produced and f l a r e d t o t h e atmosphere dur ing t h i s f ive-year t e s t i n g per iod. The r e e n t r y w e l l h a s been shu t i n s i n c e t h e 1973 p roduc t iv i ty test , with only p r e s s u r e monitor ing being conducted and small gas samples p e r i o d i c a l l y taken.

V. RADIOLOGICAL SUPPORT PLAN

A. Purpose

The purpose of this Radiological Support Plan is to establish guidelines, methods, and standards to ensure that all well plugging and site restora- tion activities to be described in Section VI are conducted in a manner that: (1) minimizes radiation exposure to participating personnel and the public, (2) eliminates radiological contamination in excess of DOE criteria at the Gasbuggy site, and (3 ) is technically and economically feasible.

B. Current Radiological Conditions

The extent and levels of surface contamination at the Gasbuggy site have been documented by soil and water sampling programs and site surveys by the Environmental Protection Agency (EPA), EPNG, and DOE, Analyses from these surveys have indicated that there is no radiological contamination of soil or surface waters exceeding DOE site disposal criteria set forth i n Tables 1 and 2 , Sect ion V . E .

Radiological contamination in excess of DOE criteria is expected on interior surfaces of the gas production-testing system from the GB-ER well bore tubing through the flare stack. In addition, a small quantity (approximately 5 to 10 barrels) of tritium-contaminated liquid is contained in the 100-barrel water storage tank.

C. Personnel Safety

1. Bioassays

All operating personnel, i.e.,l those handling or controlling the handling of contaminated material, will submit a urine sample to Eberline upon arrival at the worktsite and again upon permanent departure from the site. operational conditions. required.

If the concentration of tritium in this sample exceeds 5,000 dpm/ml, the decontamination process should be repeated, with DOE'S concurrence, until it is determined the item cannot be decontaminated to an acceptable level for unrestricted use at a reasonable cost. In addition, representative wet swipes of the accessible inner and outer portions of the item being tested will be taken.

Most of this water should be collected and a one cc aliquot

Soil samples were collected on a 50-foot grid pattern at a 2-foot depth and analyzed for tritium. expected to be more highly contaminated. Results indicated that no samples exceeded approved cleanup criteria.

A finer grid pattern was used in areas

During this final cleanup operation, a complementary 50-foot grid pattern will be sampled near the surface. More extensive sampling will be used in areas expected to be of higher contami- nation. Additional samples will be collected as prescribed by the ROS at both the surface and at depth. All soil samples will be analyzed for tritium on site and selected samples will be analyzed for 137Cs and 90Sr. samples to be analyzed for tritium is foreseen. will be conducted to delineate the extent of the contamination.

The radiologically cleared EPNG assests will be placed in the custody of EPNG at the project site for final disposition by EPNG. Radiologically cleared Government-owned equipment will be loaded onto commercial carriers and transported to the Nevada Test Site. All radiologically contaminated property will be transferred to the custody of the Government and will be appropriately packaged and shipped via commercial carrier to an approved radiological waste burial facility.

Earthwork and Revegetation

The decontamination pit will be backfilled to blend with the surrounding ground and reseeded as required. work will be kept to a minimum, but where they do occur, they will be graded and seeded.

Areas disturbed by the site abandonment

The reseeded areas will not require protective fencing.

The one-mile access road extension from the edge of the Carson National Forest boundary to the GZ area, as well as other minimal dirt roads, will be left as is.

Site Monumentation

An existing pipe frame located approximately 200 feet east of the GB-E wellhead consisting of a horizontal steel pipe supported by two vertical pipes will be left in place for use by the U.S. Forest Service. A 4-inch- diameter pipe with 4 feet protruding above finished grade and labeled with the well name will be placed over Wells GB-1, 2 , 3 , and D. A concrete monument containing a metal plaque with an inscription denoting the historical significance of the site will be erected over the abandoned emplacement well. The inscription, which will also specify certain subsurface excavation and drilling restrictions, shall read as follows:

PROJECT GASBUGGY NUCLEAR EXPLOSIVE EMl?LACEMENT/REENTRY WELL (GB-ER)

B. Analyses 0 The depth to water (head), temperature in C., pH, and electrical conduc-

tance are recorded at the time of collection. All samples are analyzed for gross alpha and gross beta radioactivity and for gamma-emitters by gamma spectroscopy. All samples are analyzed for tritium, first by the conventional method for the purpose of screening, and then those samples having concentrations less than the minimum detectable concentration are analyzed by the enrichment method.

Based on the results of these analyses, any suspect samples will be analyzed for additional appropriate specific naturally occurring or man-made radionuclides.

C. Reports

The EPA Environmental Monitoring and Support Laboratory, Las Vegas (EMSL-LV), shall prepare annual reports which contain the following:

1. Description of the sampling. network,

2 . Results, with a comment on analytical techniques used and degree of accuracy achieved.

The only a l t e r n a t i v e t o t h e proposed a c t i o n is t o t ake no ac t ion . t h e proposed a c t i o n a t Gasbuggy would l eave t h e i n t e r n a l l y contaminated equipment on t h e su r face a t t h e s i te , which i n a d d i t i o n t o t h e p o t e n t i a l hazard, is u n a t t r a c t i v e wi th in t h e surrounding environs.

5. Cumulative and Long-Term Environmental E f f e c t s

A s discussed previous ly , t h e proposed cleanup a c t i v i t i e s are intended t o erase any i n s u l t s t o t h e environment which s t i l l ex i s t ed from pas t a c t i v i - ties. A pool of r a d i o a c t i v i t y formed by t h i s nuclear de tona t ion is trapped i n rock 4,000 f e e t below t h e s u r f a c e and w i l l remain as a long-term conse- quence of t h e experiment. However, because of i t s depth, it w i l l be i s o l a t e d from and out of communication wi th t h e biosphere. r e l a t e d d r i l l ho le s i s intended t o p r o t e c t a g a i n s t poss ib l e environmental hazards which otherwise might occur i n t h e f u t u r e . Except f o r t h e r e s t r i c t i o n s imposed on d r i l l i n g o r excavat ion wi th in t h e 100-foot r a d i u s of t h e monument, t h e s i te w i l l be re turned t o i t s n a t u r a l state. This is intended t o b e . a n end po in t and no o t h e r a c t i v i t i e s are planned by DOE f o r t h e s i te so t h a t no cumulative e f f e c t s beyond t h i s end po in t are a n t i c i p a t e d .

6. Risk of Credib le Accidents

It is poss ib l e t h a t during disassembly and decontamination of t h e gas t e s t i n g equipment, some cleanup personel may be exposed t o tritium. While t h e levels are not known, and c a r e f u l personnel monitoring w i l l be i n f o r c e , i t i s be- l i e v e d t h a t no dose above t h e s t a t e d cri teria w i l l be accumulated by any in- d iv idua l . I f any tritium conta in ing l i q u i d s were s p i l l e d , assessment and cleanup of t h e s p i l l would be e f f ec t ed promptly.

Simi la r ly , i f during t h e t r anspor t ing of low-level r a d i o a c t i v e materials t o a s u i t a b l e r epos i to ry i n Nevada, an acc ident occurred which caused a s p i l l on t h e roadway, some human exposure could arise.

However, t h e low-level r a d i o a c t i v i t y could be s a f e l y and expedi t ious ly cleaned up and any r e s i d u a l d i l u t e d t o less than t h a t permitted i n dr inking water by s u f f i c i e n t f looding wi th uncontaminated water. long-term exposure would be expected from t h i s kind of i nc iden t .

No s i g n i f i c a n t

7. P o t e n t i a l C o n f l i c t s With Land Use and Other Programs

There are no known p lans by l o c a l , s ta te o r o the r Federal agencies which would c o n f l i c t wi th t h e proposed ac t ion . The r e t u r n of t h e land t o U. S . Fores t Serv ice c o n t r o l is c o n s i s t e n t w i th t h e arrangement agreed upon by t h e o r i g i n a l withdrawal order and r ep resen t s a l o g i c a l te rmina t ion of t h e program.

8. Conclusions and Recommendations

Considering t h e environmental s e t t i n g of t h e Gasbuggy s i te and t h e a c t i v i t i e s which l e d t o i t s present condi t ion , a g a i n s t t h e impacts which w i l l accrue i f t h e present cleanup and r e s t o r a t i o n p l an i s implemented, l e a d s t o t h e conclusion t h a t t h e , s i t e and human environment w i l l be improved. I n viewing t h e a n t i c i p a t e d impacts, i t i s obvious t h a t t h e s a f e t y , appearance and u t i l i t y of t h e s i t e w i l l be enhanced over t h e long t e r m , without s i g n i f i c a n t a d d i t i o n a l c o s t t o t h e environment.

It is recommended t h a t because t h e proposed a c t i o n does not c o n s t i t u t e a major Federa l a c t i o n , and w i l l have no s i g n i f i c a n t impact on t h e q u a l i t y of t h e human environment of t h e reg ion , an Environmental Assessment need not be prepared.
