Local conditions
Environmental conditions in Natrona County
Natrona County sits at the center of Wyoming's energy and infrastructure economy, with active oil and gas development, pipeline corridors, agricultural land conversion, and a steady pipeline of commercial and industrial construction in and around Casper. That history creates real environmental exposure for buyers, lenders, developers, and contractors: legacy hydrocarbon releases, historical industrial land use, and the presence of naturally occurring materials in regional soils are all factors that can stall a transaction or complicate a construction schedule if they surface late. Our environmental services are structured to move alongside your project timeline rather than hold it up. From transaction-driven Phase I and Phase II Environmental Site Assessments to construction-phase environmental monitoring and documentation, we provide the field work and reporting that lenders, regulators, and project teams need. Coverage in Natrona County is dispatched through our Denver regional hub, so scheduling should be arranged in advance to confirm availability and mobilization timing.
Wyoming's semi-arid high-plains climate produces soils that can concentrate certain naturally occurring inorganics, and the region's long history of petroleum extraction and associated surface infrastructure means potential recognized environmental conditions are common on undeveloped, agricultural, and transitional parcels alike. These regional factors make thorough records research and a systematic site reconnaissance — not a cursory walkthrough — the appropriate baseline for any Phase I scope.
FAQ · Natrona County
Does Wyoming DEEP or another state agency have specific Phase I or Phase II requirements that differ from ASTM E1527-21?
Wyoming DEQ does not publish a Phase I format that supersedes ASTM E1527-21, which remains the governing standard for All Appropriate Inquiries under federal CERCLA. For sites with known releases, Wyoming DEQ's Voluntary Remediation Program may impose additional subsurface investigation scope beyond a standard Phase II. We review applicable state program requirements before scoping any Phase II work in Natrona County.
How does the region's oil and gas history affect what you look for during a Phase I in Natrona County?
The Casper area and surrounding Natrona County have decades of petroleum production, pipeline infrastructure, and associated industrial activity. A thorough Phase I under ASTM E1527-21 includes reviewing historical aerial photographs, oil and gas regulatory databases, and state spill records alongside federal databases. Recognized environmental conditions tied to historical petroleum use are among the most common findings on commercial and industrial parcels here.
Can you support construction-phase environmental monitoring during grading or excavation if contaminated soil is encountered?
Yes. If grading or excavation encounters suspect material, we can provide field screening, soil sampling to applicable ASTM methods, and documentation to support waste characterization or regulatory notification. Coordination with Wyoming DEQ is sometimes required depending on concentrations and disposal options. Arranging standby or scheduled monitoring in advance through our Denver hub is the most reliable way to keep your construction schedule intact.
