Site Characterization. The process of collecting sufficient information to determine the nature and extent of contamination at the site.
Site Characterization. (a) DOE shall conduct a program of site characterization with respect to the Yucca Mountain site before it sub- mits an application for a license to be issued under this part.
Site Characterization. By November 1, 2023, PG&E will perform soil and sediment sampling and characterization of Diablo Creek within the Part 50 NRC license boundary.
Site Characterization. PG&E agrees to perform soil and sediment sampling and characterization for Diablo Creek within the Part 50 NRC license boundary by November 1, 2023. PG&E will conduct sampling in Diablo Creek consistent with NUREG-1575 and the Multi-Agency Radiation Survey and Site Investigation Manual for radioactivity and California Environmental Protection Agency guidance for hazardous materials. PG&E’s agreement to perform soil and sediment sampling and site characterization for Diablo Creek within the Part 50 NRC boundary by November 1, 2023, resolves disputed issues regarding site characterization for purposes of this 2021 NDCTP.
Site Characterization. Groundwater samples collected from the Mt. Olivet Cemetery irrigation well from 1990 to 1999 by UDEQ and the Salt Lake Department of Public Utilities exceeded the federal drinking water standard for PCE although no one was using the water for that purpose. PCE levels ranged from 11 to 184 micrograms per liter (µg/L) during this period of time. The irrigation well is approximately 470 feet deep and is screened the majority of its length through both unconfined and deeper confined aquifers (UDEQ 2000). In 1997, PCE was also detected in Salt Lake City municipal supply well No. 18 (SLC Well 18) at 0.6 µg/L, which is below the National Drinking Water Standards Maximum Contaminant Level (MCL) of 5 µg/L. In 1998, EPA conducted investigations in the area which included the installation of six groundwater monitoring xxxxx; one on VAMC property (MW-05) and five to the west-southwest (MW-01s, MW-01d, MW-02, MW-03 and MW-04). In September 1999, EPA MW- 03 was abandoned and an additional monitoring well (MW-06) was installed in the xxxxxxxxx xxxxxx xx Xxxxxxxxx Xxxx (XXXX, 0000). All EPA monitoring xxxxx are located southeast of SLC Well 18. Analytical results for groundwater samples collected from these xxxxx ranged from below laboratory reporting limits to 320 µg/l. Groundwater modeling representative of 1999 conditions was also conducted for SLC Well 18. The study indicated that local groundwater flow direction was to the northwest due to localized mounding. The data suggested a possible correlation between prolonged pumping and detection of PCE in SLC Well No. 18 (Xxxxx and Xxxxxxx 2004). A Site Inspection (SI) was conducted at the Site in October 2004 jointly by the UDEQ and EPA Federal Facilities Program. During this sampling activity, PCE was detected in SLC Well 18 at a concentration of 2.23 µg/L. The highest detection of PCE (128 µg/L) was found in a sample collected from Mount Olivet Cemetery irrigation well. A duplicate of this sample contained 92 µg/L of PCE. A Hazard Ranking System (HRS) package was prepared to determine if the Site was eligible for inclusion on the National Priorities List (NPL). The HRS site score was 50.00 based on the groundwater migration pathway. Any site scoring of 28.50 or greater is eligible for the NPL. EPA may propose adding sites scoring greater than 28.50 to the NPL through proposed rulemaking in the Federal Register following a QA review and public comment (EPA 1992). In June 2010, a Chevron pipeline near the mouth of Red But...
Site Characterization. Phase 1 Assessment The City of Beaverton anticipates conducting up to four Phase I assessments (two hazardous substances and two petroleum) at an estimated cost of $5,000 each. The sites will be verified with the Region 10 EPA officer and Oregon DEQ prior to assessment. The information collected will be used to determine the top priority sites for the Phase II ESAs. The project manager will coordinate the fieldwork with the contractor. The project manager will also ensure that all requirements relating to Endangered Species Act, National Historic Preservation Act, and Clean Water Act Section 404, is met by the contractors prior to commencement of fieldwork.
Site Characterization. Phase 2 Assessment The City of Beaverton anticipates conducting up to two (2) Phase II ESAs under the Petroleum grant at an average cost of $24,750 each, and five (5) Phase II ESAs under the Hazardous Substance grant at an average cost of $24,750 each, subject to change as more is discovered through Phase I assessments. The city will re-use the candidate site identification prioritization and selection criteria, which will be reviewed, added to, subtracted from, and weighted during the Community Engagement Process outlined in the upcoming Public Involvement Plan (PIP). The Project Team will, through the project manager, prepare a Quality Assurance Project Plan (QAPP), a Health and Safety Plan (HASP), and a Sampling and Analysis Plan (SAP) for each site where a Phase II ESA will be performed. These plans will identify and establish practices and procedures to assure that the overall project will be implemented in a manner that provides acceptable, useable results according to the U.S. EPA guidelines and recommendations. The plans will be submitted to the EPA and Oregon DEQ for review and approval prior to performance of any sampling. Environmental assessments under this project will be conducted by qualified contractors and in accordance with the EPA‘s All Appropriate Inquiries Final Rule.
Site Characterization. Phase II Assessment The objective of this sub task is to conduct Phase II environmental site assessments as needed to advance the assessment and characterization of the selected properties. The Phase II assessment activity is the primary use of funding for this project. In certain cases the Phase I assessment may recommend a Phase II study or the selected property may have already received initial Phase I assessment. In any event, the Coalition will work with the EPA Project Officer and IDEQ to identify and prioritize the sites that will be qualified for Phase II assessment activity. The lead entity for the Phase II assessment activity will be the Coalition’s selected environmental consultant(s), who shall be responsible for ensuring that all assessments are conducted in conformance with applicable EPA and IDEQ standards. The proposed budget for Phase II site assessments is $320,000 total, comprised of $52,500 from the petroleum budget, $267,500 from the hazardous waste budget. Specific milestones and deliverables for this subtask include: Minimum 5 Phase II Assessments completed.
Site Characterization. (a) Prior to submittal of an applica- tion for a license to be issued under this part DOE shall conduct a program
Site Characterization. As a first step, a general characterization of the trials sites would be undertaken in 10 locations. A GPS would be used to establish the geographical coordinates (longitude, Latitude and altitude) of the trials locations. Where available, weather data (or information about long term weather records or access to daily meteorological records), daily rainfall, minimum and maximum air temperatures, solar radiation or sunshine hours, relative humidity and evapotranspiration as well as presence of pests and diseases will be collected. Soil information on physical and chemical properties, classification according to local and international standards, and agro-ecology of the trial sites and any other relevant information will be recorded and uploaded to the AgTrials web application.
