y % r7othe south are low density, single family residences, some with second unit dwellings. Cmmercial and industrial facilities exist to the north, along with the town of Clements. These commercial facilities are to the northwest by greater than a mile and cannot affect the site. The region has been dry-land farmed since the middle-to-late 1800's. The area recently became irrigated in the late 1980's to early 1990's. There has been agricultural production on, and in the vicinity of the subject site since this time. INFORMATION FROM SITE RECONNAISSANCE AND INTERVIEWS The following information was obtained visually or through interviews with Mr. Bronson Van Wyck, Mr. Charles Hammond and Mr. Brad Lange: The property contains no underground or C above ground storage tanks (USTs/ASTs) and apparently never has. This is documented by the fact that although Mr. Van Wyck has owned the property for the past six months, Mr. Charles Hammond, who is an agricultural appraiser, has direct knowledge of the property for the past 14 years and has first-hand knowledge that no tanks have been on the property during this time. The previous owner prior to Mr. Van Wyck was Mr. John Teresi. Mr. Teresi bought the property in 1992. The vineyard has been farmed by Mr. Brad Lange for Mr. Teresi since 1992, and subsequently for Mr. Van Wyck upon his acquisition of the property. Mr. Lange, of the custom farming company LangeTwins, Inc. has provided all of the agricultural information on the property under examination. He has stated that no agrichemical mixing has taken place on the property primarily because: 1.)No well exists to pump mix water, and 2.) The fact that all mixing takes place at the LangeTwins centralized locations where mixing is done under controlled conditions (e.g.,runoff control, drift control, water supply with air gaps/backflow devices, access to proper Personal Protection Equipment- PPE). A list of agrichemicals applied to the property is discussed in the next section. It is a possibility that minute volumes of agrichemicals sprayed on the property acreage may drift C to surrounding properties. The site can be considered in the predominant downgradient windshed to additional vineyard acreage. In addition, the San Joaquin County Mosquito Abatement District may spray for mosquitos in the ditches surrounding the land. The entire acreage was walked and surveyed for evidence which may suggest surface and/or subsurface contamination: No containers were observed nor was there evynce-- olid_waste disposal.

None of Ih.Up environmental indicators werepresent. As evidenced by the attached photographs, no hazardous materials are'stored on-site and there were no indication or observations of spills or other items associated with hazardous materials. None of the vines showed signs of stress induced by environmental contamination. An important concern associated with the environmental assessment of open properties is the issue of buried pesticide containers or discarded items. It was an occasional practice to dispose of containers or discarded items by this method many years ago. Page -2- Chesney Consulting
