INPR, Tomales Bay Bombing Target appears that the Abbott's Lagoon Bombing Target was not used after that date. Since no hazardous exposure pathway exists, no Department of Defense Action is Indicated (NDAI) for this area. Tomales Point Aerial Mine Laving - Range: - On 16 October 1956, Tomales Point Aerial Mine Laying Range was established west of Tomales Point. It covered an area approximately 28,000 feet long and varied from 7,000 to 12,000 feet in width and was located more than 100 yards from the shoreline. No explosives were to be used. During mine laying exercises, wooden markers three inches in diameter, 14 inches long, and weighing approximately five pounds were dropped into the Pacific Ocean. The wooden markers contained a small quantity of chemicals that produced smoke upon contact with salt water. Prior to March 1957, three rake stations were established to observe the exercises at the Tomales Point Aerial Mine Laying Range. They were to be known as Monuments Dave, Goat, and John (NAS Alameda, 15 March 1957). To date no leases permitting Government use of these properties have been located. The Tomales Point Aerial Mine Laying Range is not eligible for DERP-FUDS funding. Since the range is beyond 100 yards of the mean high tide, it is an ineligible property under the DERP-FUDS Manual, July 1996, Section 3.2b(l), "clean-up of off-shore ordnance properties, beyond 100 yards of mean high tide, will not be eligible, except in special cases where a public exposure pathway exists." Since no such pathway exists for the Tomales Point Aerial Mine Laying Range, the property is ineligible. SIm VISIT: Two site visits were conducted at each site. The first occurred on 8 April 1998 when TechLaw Inc. (TechLaw) was contracted by the USACE to prepare a Preliminary Assessment Report (PAR) for the sites. The second visit occurred on 29 April 1999 when USACE representatives visited the site. TechLaw 4
INPR, Tomales Bay Bombing; Target 5 Messrs. Gene Barber and Steven Clonts of TechLaw began the site visit on the east side of Tomales Bay. TechLaw then proceeded to the area just east of Hog Island and viewed the area near the location of the Tomales Bay Bombing Target. Tomales Bay is a very shallow body of water, and TechLaw observed that at low tide several fishing boats were left in the mud. The southern end of the bay is the most shallow. Oyster farms are located in this area. There are motels, a few small marinas, and a yacht club on the western side of the bay. TechLaw finished the site visit at Abbotts Lagoon. The trail to Abbotts Lagoon is bordered by a cattle ranch and appears to be less frequently traveled than the trails on the headlands. As a result of the site visit, Techlaw developed the following conclusions: The Point Reyes National Seashore is widely used by the public for recreational purposes, and the historic cattle ranches and dairies are still in operation over most of the site. The trails on the Point Reyes headlands are heavily traveled by park visitors. All of the bombing targets referenced in this report have been removed. Several of the structures historically utilized by the Government still stand on the Point Reyes National Seashore. No evidence was discovered of live ordnance at any of the aerial bombing target areas investigated (TechLaw Inc., 1998). USACE. Environmental Design Section (EDS): The site visit for the USACE was conducted on 29 April 1999, by Ms. Tracie Billington and Mr. Scott Duen of the USACE, and Mr. Clinton Huckins, USACE Unexploded Ordnance (UXO) Safety Specialist from Fort Ord, California. The USACE representatives arrived at Pierce Point Ranch, and then hiked up Tomales Point trail to the north, to get a better view of the Tomales Bay Bombing Target location. From the top of the hill just east of the trail, Hog Island and all of Tomales Bay could easily be seen to the east, and the general area where Tornales Point Aerial Mine Laying Range existed could be seen to the west. Two photos were taken of Hogs Island and the bay (Photograghs 1&2). A Global Positioning System (GPS) instrument was used to obtain the coordinates of the location on top of the hill overlooking the bay. The reading that was recorded at this location was Lat. 38" 11'North
