Throughout his career, Mr. Brown has been involved in a diverse mix of projects, including asset-management studies, geotechnical-laboratory work, environmental assessments, slope-stability analyses, and geotechnical settlement determinations. In particular, Mr. Brown was responsible for assessing slope-stability and anticipated settlement for several landfills in California. This information was used for general waste-placement planning purposes and to develop Corrective-Action Plans, which are designed to be implemented in the event a natural event (e.g., an earthquake) causes structural damage to the landfill.
Mr. Brown’s work in environmental assessments includes his term as project manager for the composition of three technical impact studies regarding a proposed solar energy project near Barstow, California. These studies were undertaken to perform an Environmental Assessment pursuant to the California Environmental Quality Act (CEQA). The studies performed were 1) an Air Quality/Greenhouse Gas Assessment, 2) a Transportation/Traffic Assessment, and 3) an Aesthetics assessment. Mr. Brown performed the Air Quality/Greenhouse Gas Assessment himself, using the computer program CalEEMod to quantify the anticipated air pollutant and greenhouse gas emissions from the construction, operation, and decommissioning phases of the project. These figures were compared with the thresholds-of-significance promulgated by the regional air quality management district and county greenhouse gas management plan to determine if building the project would impart significant air quality impacts and whether mitigation measures would be required. For the Traffic/Transportation and Aesthetics Assessments, Mr. Brown coordinated with sub consultants to ensure that the project parameters were understood and accurately considered. These efforts resulted in three technical reports which substantiated the CEQA Initial Study determinations of significance made for the assessments’ respective sections in the CEQA Initial Study Guidelines.
As a Nevada Certified Environmental Manager, Mr. Brown has conducted numerous Phase I Environmental Site Assessments. Each assessment requires proper discernment regarding the historic and present uses and attributes of a property and its vicinity to identify factors that pose environmental risks to the property. Mr. Brown is also skilled in conducting Phase II Environmental Site Assessments. The primary goal of a Phase II Environmental Site Assessment is to better understand the environmental risks identified in a Phase I Environmental Site Assessment; this is commonly accomplished through the sampling and testing of media such as soil or groundwater for suspected contaminants. Mr. Brown has particular experience in assessing and managing the risks that underground storage tanks, such as those used to store heating oil, pose to properties.
