Site Background. 2. Auburn Oak Builders, Inc. was, at all relevant times, the owner and developer of the Oakcrest Estates construction project (Project). The Project involved construction activities on and around certain lands in the area of Ventura County Assessor’s Parcel Numbers 032-0-221-265, 032-0-222-105, and 032-0-221-275, commonly known as 00000 Xxxxxxxx Xxxxxx, 00000 Xxxxxxxx Xxxxxx, 0000 Xxxxxxx Xxxxx, and 00000 Xxxxxxxx Xxxxxx xx Xxxxxxx Xxxxxx xx Xxxx, Xxxxxxxxxx (Site).
3. On September 2, 2009, the California State Water Resources Control Board (State Water Board) adopted Order No. 2009-0009-DWQ (as amended by Order Nos. 2010-0014-DWQ and 2012-0006-DWQ), National Pollutant Discharge Elimination System (NPDES) General Permit for Storm Water Discharges Associated with Construction and Land Disturbance Activities (General Permit). The General Permit regulates storm water discharges to waters of the United States from construction sites that disturb one or more acres of land surface or that are part of a larger common plan of development or sale of one or more acres of disturbed land surface.
4. On January 30, 2019, Xxxxxxx Xxxxx, Xx. principal and Chief Executive Officer of Auburn Oak Builders, Inc. and the designated Legally Responsible Person (LRP), submitted a Notice of Intent (NOI) to comply with General Permit requirements to the State Water Board’s Stormwater Multiple Application and Report Tracking System (SMARTS) and was issued Waste Discharge Identification (WDID) 4 56C383177 upon permit enrollment.
5. General Permit section V.A.2. requires the implementation of best management practices (BMPs), using best available technology economically achievable (BAT) and best conventional pollutant control technology (BCT) to reduce pollution from storm water runoff from construction sites. The General Permit prohibits all discharges except for storm water and non-storm water discharges specifically authorized by the General Permit or another NPDES permit. (General Permit, III.B.)
6. Runoff from the Site flows to Skyline Drain and ultimately to the area between San Antonio Creek and Camino Cielo Road, which is part of Ventura River, Reach 4. The pollutants in the runoff from the Site have the potential to impact the beneficial uses of Ventura River, Reach 4.

Site Background. (Compendium Sections 5, 6, and 7) The analysis of the existing Site details must be included in the FSP. This analysis shall include a conceptual site model (“CSM”) that describes the Site and surrounding areas, discusses known and suspected contaminant sources, characterizes the state and transport of contaminants, identifies potential exposure pathways and likely receptors (human and ecological), and includes other information regarding the physical and chemical conditions that may affect contamination at the Site. The FSP shall also include descriptions of specific data gaps and ways in which SRI sampling is designed to fill those gaps.
Site Background. 2. The Discharger owns the property at 0000 Xxxxx Xxx, Xxxxxxx Xxxxx, Xxxxxxxxxx, Xxxxxx of Orange (Site). Until 1987, the Site was owned by Xx. Xxxxxxxx XxXxxxxxx. When Xx. XxXxxxxxx passed away, the Site was transferred to the XxXxxxxxx Trust where it was held until the Discharger acquired the Site in 2002.
3. Historically, Newport Plating operated a plating shop at the Site between the early 1950s and 1988. Xx. XxXxxxxxx leased the Site to Newport Plating. Newport Plating’s operations included brass, cadmium (Cd), copper (Cu), chromium (Cr) or “chrome,” gold (Au), nickel (Ni) and silver (Ag) plating; chrome and paint stripping; and steel passivity. After the plating operations ceased, the subsequent utilization of the building has been general office and business activities.
4. The groundwater flow from the Site is tidally influenced by the body of water in the adjacent the Rhine Channel and generally flows northwest or southeast of the Site during high and low tide, respectively. Groundwater is typically encountered at 4 feet below ground surface (bgs) and fluctuates diurnally with the Rhine Channel. The upper 2.5 feet of soil consists of man-made fill and from 4-5.5 feet bgs consists of highly permeable fine-grained to coarse sand. Due to the characteristics of the groundwater flow at the Site, there is an increased likelihood that groundwater has been, and continues to be, impacted by the ongoing discharge of contaminants from the Site and into the underlying groundwater.
5. Several phases of soil and groundwater investigation at the Site detected “Title 22 metals” (as defined in California Code of Regulations, Title 22), and cyanide. Historic groundwater concentrations of these constituents exceeded the maximum contaminant levels (MCLs) and action levels (ALs) for drinking water, as defined by the California Department of Public Health (now the State Water Resources Control Board [State Water Board] Division of Drinking Water [DDW]). Historic soil concentrations at the Site exceed the current residential Environmental Screening Levels (ESLs), as set forth by the San Francisco Bay Regional Water Quality Control Board in 2016, for Cd, hexavalent Cr (Cr6+), Cu, Lead (Pb) and cyanide.
6. On March 17, 1987, staff from the Orange County Health Care Agency (OCHCA) observed wastewater from Newport Plating’s metal finishing operation, ponded in, and leaking from an outdoor area at the Site due to inadequate secondary containment. Samples of the contaminated ...
Site Background. 2.1 Site Description The Forest Park Property at NW Yeon/Hwy 30 (Site) is an undeveloped area on the west side of the 4400 block of NW St. Helens Road, at the intersection of XX Xxxxxxxxx and NW Yeon Avenues (Figure 1). The Site consists of three separate parcels (Tax Lots 100, 200 and 300) and totals approximately 3.9 acres (Figure 2). The lower portion of the Site is flat and then steeply slopes uphill. A gravel and dirt access road to Forest Park (Fire Lane 1) enters the Site at the southeastern corner and bisects Tax Lots 100 and 200 before exiting the Site on the western boundary. Vehicle use of the gravel road is restricted to City of Portland staff access; public motorized access to the Site was closed with the installation of eco‐block barriers along NW St. Helens. There is a perennial stream that enters the Site on the western boundary and flows north to a ditch on the adjacent property that discharges to the municipal stormwater conveyance system connected to Outfall 19 (OF 19). Surface flows from Forest Park seasonally enter and move across the Site, generally from west to east. The majority of stormwater infiltrates on Site. Tax Lot 200 includes a catch basin inlet that captures some of the surface water flowing from the hillside and conveys it to OF 19 via a piped connection to a municipal stormwater manhole (Figure 2). Native and invasive vegetation dominate the Site, and during periods of heavy saturation stormwater seasonally ponds at the bottom of the Site. The Site currently is vacant open space; there are no structures on the Site and it is not used to store or produce materials. There are no impervious surfaces at the Site. The future use of the property is for a trailhead for Forest Park that will include at a minimum a parking lot, access road and improved trails. Stormwater management features will be incorporated into redevelopment plans in accordance with City Code, and DEQ review and approval.
2.2 Site Ownership and Operating History PP&R acquired the Site in two phases. In May of 2005 PPR obtained Tax Lot 100 (2.3 acres), which was owned by Portland General Electric (PGE), under Prospective Purchaser Agreement DEQ No. 05‐01 with DEQ. In October of 2014 under Order of Consent DEQ No. 14‐02, PP&R acquired Tax Lots 200 and 300 (1.6 acres) which were owned by Xxxxxxxx Portland Properties, LLC. At the time of these acquisitions, neither property included structures or other impervious surfaces. PGE used the property for an access rout...

LFG Production Rate Estimates . Future LFG System Designs County of Santa Extraction xxxxx Collection system Blower/flare facilities Future LFG System Installation Sequencing Plan LFG System Installation/Construction Guidelines . LFG to Energy Plans In preparing the master plan, several alternative LFG extraction systems will be analyzed. Both vertical and horizontal extraction well designs will be evaluated, as well as, the appropriate placement criteria for proper installation of each type. Concurrent with the work effort regarding extraction xxxxx, various types of typical LFG control facilities and collection system details will be identified. These system details will then be compared for such factors as: • Technical effectiveness; • Reliability and history of operation; • Ease of operations and maintenance (O&M); • Cost of initial installation and O&M; and • Compatibility with existing control systems and mitigation measures. Once this evaluation is complete, a selection matrix will be prepared. This matrix will compare the well design types and collection system details to specific site conditions and designs that will be applicable to future phases of landfill expansion. It will match the type, size and configuration of each phase or module to the appropriate type of landfill gas control or recovery methodology required. It would also include such items as calculations of expected landfill gas production rates for each phase, and tables summarizing the expected installation sequencing of the various system components over time. Utilizing the matrix tool described above, the installation/construction guidelines for the LFG system will be developed. These detailed guidelines will allow County staff to anticipate, identify, and install the appropriate extraction well type and collection system components, as they are needed over the life of the site operations. The installation guidelines will include information on extraction well siting/placement considerations, system design details, material requirements, equipment selections, and brief discussions of applicable installation/construction procedures. A future construction schedule consisting of system installation milestones that are coordinated with, and based upon the landfill expansion plans and waste filling patterns will be included. I...

Site Background. Libby is a community in northwestern Montana located 7 miles southwest of a vermiculite mine that operated from the 1920s until 1990. The mine began limited operations in the 1920s and was operated on a larger scale by the X.X. Xxxxx Company from approximately 1963 to 1990. Studies revealed that the vermiculite from the mine contains amphibole-type asbestos, referred to as Libby amphibole (LA). Epidemiological studies revealed that workers at the mine had an increased risk of developing asbestos-related lung disease (McDonald et al. 1986, Xxxxxxx and Xxxxxxx 1987, Xxxxxxx et al. 1987, Xxxxxxxx 2007). Additionally, radiographic abnormalities were observed in 17.8 percent of the general population of Xxxxx including former workers, family members of workers, and individuals with no specific pathway of exposure (Xxxxxxx et al. 2003). Although the mine has ceased operations, historic or continuing releases of LA from mine-related materials could be serving as a source of on-going exposure and risk to current and future residents and workers in the area. The Site was listed on the National Priorities List (NPL) in October 2002.

Site Background. On October 15, 2012, one of 98 storage bunkers at Explo Systems Inc. site exploded prompting investigations by the EPA, LDEQ, the Louisiana State Police, and other responders. The explosion shattered windows in the City of Minden, Louisiana (approximately 4 miles to the northeast), and generated a 7,000-foot mushroom cloud. Explo Systems was under contract with the Department of Army to demilitarize surplus munitions. The State Police found 10 million pounds of unsecured M6 (howitzer gunpowder) improperly stored outside of the bunkers and 8 million pounds of a variety of other explosives improperly stored inside bunkers. To keep the residents safe due to the potential risk, the town of Doyline, Louisiana (approximately 400 homes), was evacuated during operational hours from November 28 to December 7, 2013. In addition, the Youth Challenge Program (school) and non-essential personnel at Camp Minden were evacuated. The Webster Parish Jail at Camp Minden followed shelter-in-place procedures. The State Police directed Explo Systems, Inc., to temporarily secure the M6 in available bunkers. This was completed in May 2013. In August 2013, Explo Systems Inc. declared bankruptcy and the Louisiana Military Department took ownership of the explosives at the site. EPA then initiated negotiations with all potentially responsible parties to eliminate the risks posed by the 18 million pounds of M6 and other explosives culminating in the October 28, 2014 Agreement.
