Phase I Environmental Site Assessments (ESAs), known as Phase I ESAs, are conducted in Nevada by our Certified Environmental Managers (CEMs) to evaluate potential environmental liabilities associated with a property. If any hazards are identified during this crucial part of environmental auditing, a Phase II investigation/sampling, also known as a Phase II ESA, may be necessary, which involves sample collection to determine the extent of contamination.
If contamination is found, a Phase III monitoring/corrective action/site closure plan, or Phase III ESA, may be necessary to remediate the site. Our Nevada CEMs, experts in environmental management, are trained and experienced in conducting these assessments, investigations, and remediation plans to achieve regulatory compliance in Nevada, ensuring a thorough environmental risk assessment.
Remediation strategies may include excavation, groundwater treatment, or other methods deemed appropriate based on the specific site conditions.
Phase I: Environmental Site Assessments (ESAs)
A Phase I ESA is a preliminary environmental site assessment conducted by our Nevada CEMs to evaluate the potential environmental liabilities associated with a property. The purpose of this assessment is to identify and evaluate any potential environmental risks associated with a property including the presence or likelihood of hazardous materials or contaminants, ensuring robust Nevada environmental compliance.
Our Nevada CEMs are certified in accordance with the Nevada Division of Environmental Protection (NDEP) regulations. Phase I ESAs are typically conducted as part of due diligence in Nevada property transactions or in preparation for financing.
Phase II: Investigation / Sampling
If a Phase I ESA, conducted by our skilled CEM, identifies any potential environmental hazards, a Phase II ESA may be necessary. This involves the collection of samples from the site to determine the extent and severity of any contamination in Nevada.
Robison Engineering’s CEMs are trained in site investigation techniques and sampling protocols, ensuring meticulous environmental management. The samples collected during a Phase II ESA are analyzed in a laboratory to determine the presence and concentration of hazardous materials or contaminants.
Phase III: Monitoring / Corrective Action / Site Closure
If contamination is identified during a Phase II investigation, a Phase III monitoring/corrective action/site closure plan may be necessary to remediate the site. This involves monitoring the site to determine the effectiveness of the remediation and achieving closure criteria established by regulatory agencies in Nevada.
If contamination is identified during a Phase II ESA in Nevada, a Phase III ESA (Monitoring / Corrective Action / Site Closure) may be necessary to remediate the site. This involves monitoring the site to determine the effectiveness of the remediation and achieving closure criteria established by regulatory agencies in Nevada. This comprehensive environmental auditing process helps ensure environmental compliance at every level.
Professional Engineer, President
P.E. – 25822 | C.E.M. – 2459 Julianne is a Professional Environmental Engineer and Certified Environmental Manager. She loves getting into the field to solve our most interesting environmental problems. When she isn’t in the desert chasing down noxious weeds or water quality issues, she’s in the desert racing her motorcycle…when her bones heal back up from the last race.
C.E.M. – 1512, Senior Professional Marcie (CEM-1512) began her career as a miner with geology degrees from U. of Iowa and Texas-El Paso. Her understanding of the perspectives of both the extractive and environmental protection allows her to balance and respect their common goals.
P.E. – 009674, Principal Engineer Wally Robison is the founder and now retired President of Robison Engineering Company. Wally started in the mining business in 1969, working for Gulf Resources in Montana. Going on to obtain a BS in Geological Engineering from University of Utah, Salt Lake City, Utah, in 1972. Wally is a PE of Mining and a Certified Environmental Manager. He takes pride in careful, reliable work and brings unique common sense to the environmental consulting practice. A fifth-generation Nevadan, Wally is proud to contribute to the health and prosperity of the western US.
Ph.D. Scientist Chris Ross continues his elegant and wide-arching career, now headquartering our branch “office” on the Gulf side of Baja in Mexico; he still mentors our Environmental staff and performs weed surveys and veg surveys for bond release.
