Hazelton Avenue Stockton, California 95205 Subject: Application for Encroachment Permit Moore Petroleum Bulk Plant 5491 F Street, Banta, California Apex Project#ERA02.004 Dear Mr. John Wotila: Apex Envirotech, Inc. (Apex) has been authorized by our client to submit.an application for a.permit-to encroach on public property at the above referenced site (Figure 1 and 2). As per Apex's conversation with the San Joaquin County Public Works Division (SJCPWD) on May 25, 2004, please find the enclosed material: an encroachment permit application form(Appendix A),a copy of liability insurance with San Joaquin County as additionally insured(Appendix B), a$2,000 performance bond per well in county right- of-way(Appendix C), ozone sparge well construction diagrams, and a Cal Trans designed traffic plan. 'Drilling is tentatively scheduled for October, 2004 and will last two days. This consists of four 8-inch borings along the public right of way on the east side of Sixth Street (Figure 3). Also, at a later date, two trenches 87in. wide and 18 in. deep will be cut. One trench will be in the dirt 150 feet in length paralleling Sixth Street, and the other cutting the asphalt of Sixth Street to cross its width, in order to connect ozone supply lines to the wells (Figure 4). Trenching will also be a two-day project. Each occurrence will involve a temporary lane closure along the effected section of roadway. Traffic Plan: The proposed traffic plan is based on Chapter 5 of the California Department of Transportation's standard Traffic Operations manual, in concern of public safety and traffic flow (Figure 5). For all proposed activities, arrangement of traffic channeling equipment is dependent on a varying work area length. The lane closure length will be kept minimal, allowing 25 feet of buffer space between actual work area and the end of the lane taper.
