Page 2 of 3 (drilling or trenching)work in the east railroad easement(I do not want to turn a$30K investigation project into a$1M clean-up and repair project). • Bob Jones showed us aerials photographs of the site taken from the 1930s(the photographs were 1:10,000 and showed a 1 mile grid—low resolution quality; Sabra provided a DVD of digital high- resolution historical aerial photographs to Bob from the investigation • Bob Jones stated that Beth could come up to review the development drawings and get scanned copies of the drawings and photographs(we can schedule a day to perform this prior to doing the site staking for boring and trench locations) • Nick Jones had several questions with regard to the placement of gas monitoring wells at the site and rationale—we stated that the 3 wells proposed for the subdivision would provide us with the best data on whether LFG was impacting the subdivision and also was the least difficult to access for monitoring (versus placing on private residence properties); Nick suggested wells on the railroads west easement— which has trenches currently proposed • Bob Jones showed photographs of the site as it was being developed—he showed photographs of: o the finished grade for the development(note that a cut and fill project was used to achieve grade —the site was not leveled and brought up to grade—thus pockets of waste could still exist at the site(could a resistivity geophysical survey along the streets be useful to show a section of the subgrade—its either going to be uniform or show anamalies?); o installation of a 24-inch concrete storm drain (in a trench approximately 5 feet in depth)—he stated that only native Lodi loam soils were encountered in excavation of this trench which run from Turner Road to the river under River Pointe Place (Street);recommend that the LEA periodically check(monitor)the storm drain vault boxes to determine if any explosive or oxygen deficient conditions exist—given that the pipe utility is 6 feet below grade in native soils( e may check during the investigation) o his property during clean-up activities(he stated that the site superintendent had found some waste on his property toward the river—which was cleaned up); note that this indicated that some disposal had occurred on the west side of the railroad tracks o the soil berms(constructed of Lodi clean soils)associated with containment structures for the winery above ground processing tanks River Point Subdivision Homeowners Association Meeting(37 River Pointe Place)—8 Feb 2012 • A regularly scheduled HOA meeting was conducted at a HOA members home—the meeting was attended by CalRecycle staff(Steve Levine,Sabra Ambrose and Glenn Young),the LEA(Robert McClellon and Natalia Subbotnikova),the HOA board and residents of River Pointe Subdivision. • Sabra provided a presentation to the HOA on the landfill investigation and schedule; she also explained the location of trenches and borings proposed and the specific boring and trench locations in the River Pointe Subdivision. She summarized the field work to be performed and also discussed the site access agreement; she answered questions on warrantee issues with respect to ensuring that the street was replaced to its original condition • Several homeowners asked if the wells in the subdivision could be delayed after work at the landfill was completed (a two phased approach); I answered that the work in the subdivision if delayed,would have to be done at another time (due to our contract with Ninyo& Moore expiring—and a new contract not being in place until May); I told them the work may still be required by the LEA and could potentially be the responsibility of the home owners(based on the waste footprint extending into the River Pointe Subdivision property);there is still based on the aerial photographs—evidence that the property on the west and east side of the rail road tracks(adjacent to the River)was one property while disposal activities were taking place; in the 1950s the property appears to be the landfill on the east side of the tracks and the winery on the west side of the tracks(potentially a subdivision of the property occurring). • There were questions concerning finding contamination in the Subdivision and consequences for real 2/9/2012
