<br /> accidents at file landfill or during taste transport c+sL cause injury, t,) site workers, the general
<br /> public, or the environment. The Site Operations Plan tiva�, completed in 1y96. The California
<br /> Administrative Code of Regulations was modified to consolidate l'itle 14 and Title 23 into_) Title
<br /> L 27; this was an administrative improvement to) cr)nst)likiate thr RVVQCB acid C1WMB
<br /> requirements for landfills,ensuring that reporting and subm.issioms of data are no)t redundant.
<br /> Mitigation Measures L.3(a), (b), (c), (d) and (e) of the Mitigation Monitoring/Reporting Program
<br /> would reduce this impact to a less-than-significant level.
<br /> c. Less than Significant Impact with Mitigation hworporatiorl: Additional landfill gas would be
<br /> generated, thus increasing the potential for explosion .hazards. The suggested landfill gas
<br /> control installations bi the 1994 FIR have already been implemented, along with the training of
<br /> the operators. These are documented ill the 1996 Austin Road Landfill Disposal Site
<br /> Information report. In addition to the installation suggested in the 1994 E1R, some additional
<br /> landfill gas extraction wells were installed, .responding to the discovery of elevated gas levels
<br /> (beyond that allowed by the regulatory community) emanating from the northeastern part of
<br /> the landfill. The reporting of these higher gas levels was reported to the CIWMB. In early 1998
<br /> the C1WMB, mainiv in response to the gas detections in the .northeast part of the landfill, issued
<br /> a formal SWM Order to the Cite. The Order included entering into a scheduled compliance
<br /> agreement. By October 1995, in response to the higher than permissible gat, detections reported
<br /> in the northeastern part of the landfill, and xvith the approval of the ClVVMB, the Cite installed
<br />! and brought on i.ine an additional 12 vapor extraction wells to complement the existing gas
<br /> collection systerin. Mitigation Measures LA(a), (b), (c), (d), (e), (f), anon(g) of the Mitigation
<br /> Monitoring/Reporting Program would continue to reduce this impact to a less-than-significant
<br /> i
<br /> level.

<br /> d. Less Than Significant with Mitigation hioo rpo)ration: Because the project site includes an

<br /> 65962.5. Compliance with existing regulations and permit requirements, i:nClUding the San
<br /> Joaquin County Public Health Services Solid Waste Facilities Permit 111111 and the State Water
<br /> Resources Control Board (SWRCB)/Central Valley Regional Water-Quality Control Board
<br /> (RWQCB) Waste Discharge Requirement; the operating and ellvii'onnlental monitoring
<br /> procedures described in Fina l Design Study Deport fou' the Austin Road Landfill Expansion (R.
<br /> W. Beck and Associates,June 1993); and the.mitigation measures specified i.n the Mitigation
<br /> Monitoring/Reporting Program, including Mitigation Measures K.2(a), (b), and (c), K.5(a), (b),
<br /> (c), (d), and (e), K.6(a), K.5(a), (b), (c),and (d), L-1(a), (b), (c), (d), (e), (0, and (g), L.2(a), (b),and
<br /> (c), L.3(a), (•b), (c), (d), and (e), LA(a), (b), (c), (d), (e), (f), and (g), and L.5(a), (b), (c), and (d), and
<br /> K.8(a)'and (b) of the Mitigation Morlitorill-/Reporti,lg Progra.nl, would reduce the impacts to a
<br /> less-than-significant level.
<br /> e. Less Than Significant with Mitigation lncorporation: As stated in the FIR, the proposed
<br /> project would expand landfill activities withiai 10,000 feet of a Stockton Metropolitan Airport
<br /> runway. The Airport has not experienced problems tivith landfill-related bird hazards to
<br /> aircraft. Therefore, it is not anticipated that proximity of airport operations would result ill a
<br /> safety hazard to landfill workers or visitors. Furthermore, Mitigation Measures A.3(a), (b), (c),
<br /> and (d) of the Mitigation Monitoring/Reporting Program are intended to prevent future safety
<br /> hazards, and would reduce impacts to a less-than-significant level.
