“…Seismic reflection data (Hern et al, 1979) later collected over breccia pipes showed no distinctive signature. Because of the high cost and possible ineffectiveness, seismic reflection was not used to screen the site area for undiscovered breccia pipes.…”

“…A general seismic reflection survey was conducted over parts of the WlPP site during 1976 (07/21/76; WP01847; also see Hern et al, 1979). The referenced memorandum by McMillan, discussing and interpreting the seismic data, shows that the survey was conducted mainly to determine the overall stratigraphic continuity and structural disturbance of beds at or around the WlPP site.…”

“…The initial interpretive data and accompanying report (07/21/76, WPOl847) were prepared by a consulting geophysicist (Colin McMillan) under contract to Sandia while a separate company (Dresser Olympic) was contracted t o acquire the data in the field. McMillan also was responsible for supervising data collection in the field (Hern et al, 1979).…”

“…New seismic reflection data were collected during 1977 over the sites of "known breccia pipes" at Hills A-D and the "Weaver pipe." Although this can be directly inferred from the location of seismic reflection lines X-IO, X -I 1, X -I 2, and X -I 3 (Hern et al, 1979), no documents prior to the fieldwork have yet been recovered that specify this work included a test of technique against "known breccia pipes." As part of a broader field program of collecting seismic reflection data at or around the WlPP site, these four lines were meant t o determine the capability of this technique t o detect breccia pipes where they were known t o exist.…”

A portion of the WIPP site has been extensively surveyed with high-precision gravity. The main survey (in T22S, R31E) covered a rectangular area 2 by 4-1/3 mi encompassing all of WIPP site Zone II and part of the disturbed zone to the north of the site. Stations were at 293-ft intervals along 13 north-south lines 880 ft apart. The data are considered accurate to within a few hundredths of a milligal. Long-wavelength gravity anomalies correlate well with seismic time structures on horizons below the Castile Formation. Both the gravity anomalies and the seismic time structures are interpreted as resulting from related density and velocity variations within the Ochoan Series. Shorter wavelength negative gravity anomalies are interpreted as resulting from bulk density alteration in the vicinity of karst conduits. The WIPP gravity survey was unable to resolve low-amplitude, long-wavelength anomalies that should result from the geologic structures within the disturbed zone. It did indicate the degree and character of karst development within the surveyed area. r NOTSCE PffprmMR nP THIS REPORT ABE lUEfilBlE.

The Delaware Basin is a broad asymmetric sedimentary trough in southeastern New Mexico and west Texas. Basin subsidence occurred from the Pennsylvanian into the Triassic. The basin also underwent tilting since the early Cenozoic. Layered evaporite units of Ochoan age in the basin are 1000 m thick. These evaporites are divided into three stratigraphic units (listed in order of increasing age): the Rustler Formation, the Salado Formation, the Castile Formation. These units, especially the Castile, are deformed along portions of the margin of the Delaware Basin and in some areas internal to the basin. In the northern Delaware Basin adjacent to the WIPP site, the term "Disturbed Zone" (DZ) has been applied to an area in which deformation structures are found in boreholes and from which chaotic seismig reflection data were obtained. The origin and timing of this deformation is considered important for the determination of This docunlent is PUBLI&'L%7 RELEASABLE Authorizing Official Date: 81/31 / W O d
