Site Characterization. Phase II Assessment
Site Characterization. The process of collecting sufficient information to determine the nature and extent of contamination at the site.
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. Based on past studies of burned residential homes and structures from large-scale wildland fires, the resulting ash and debris from residential structures burned by fires can contain toxic concentrated amounts of heavy metals such as antimony, arsenic, cadmium, copper, lead, and zinc. Additionally, the ash and debris may contain higher concentrations of lead if the home was built prior to 1978, when lead was banned from household paint in the United States. The presence of these heavy metals can have significant health impacts on individuals, individual properties, local communities, and watersheds if the ash and debris are not removed promptly. The residual materials, including, but are not limited to, stucco, roofing, floor tile, linoleum, fireplaces, furnaces, vinyl tiles and mastic, sheetrock and joint compound, cement pipe, exterior home siding, thermal system insulation, concrete and mortar, and other building materials commonly used in homes built before 1984. These residual materials may also contain other chemicals of concern such as asbestos. Additionally, wildland fires can kill or seriously damage a great number of trees, resulting in a significant risk to the public as the impacted trees are more likely to fall onto public thoroughfares and other infrastructure.
Site Characterization. As part of the RI, Respondent shall perform the activities to describe areas of a Site that may pose a threat to human health or the environment through the following:
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. (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.
(b) DOE shall conduct the investiga- tions to obtain the required informa- tion in a manner that limits adverse ef- fects on the long-term performance of
Site Characterization. The objective of this task is to characterize the extent of hazardous substance and hazardous waste contamination at the Property or group of Properties. This task may be conducted in sequential phases, such as a separate soil or groundwater investigation.
