His work includes litigation support, due diligence, audits and interactions and negotiations with regulatory agencies. Roberto has also testified as an expert witness on air quality matters, including emissions estimates and air dispersion modeling.
Previously, Roberto served as an air team leader in Spirit Environmental’s Houston office, providing air quality consulting support to a variety of industries, including chemical and petroleum storage terminals, oil and gas production and processing, industrial manufacturing and food production facilities. He has led permitting projects at multiple levels, including air quality Permits by Rule (PBR), Standard Permits, New Source Review (NSR), Nonattainment New Source Review (NNSR) and Federal Title V permitting. His permitting experience spans multiple states across the United States, including Texas.
Roberto also conducts and directs computerized air dispersion modeling initiatives in support of client projects and has developed methods to streamline these evaluations to improve project efficiency and outcomes. In addition to permitting, his experience includes regulatory applicability assessments for state requirements, NSPS, NESHAP and MACT; development of calculations and spreadsheets for air emissions recordkeeping; continuing compliance; periodic reporting; and emissions inventories.
Beyond traditional air quality permitting and compliance, Roberto has conducted air quality impact evaluations in support of EPA Risk Management Plans (RMPs) and Railroad Commission oil and gas contingency plans.
