Senior Chemical Engineer

I particularly enjoy ERG’s collaborative, creative work environment. Every day I look forward to working with ERG clients and colleagues to develop efficient, data-driven approaches to solving environmental problems.

Lori Weiss (she/her/hers) has over 25 years of experience supporting development of federal environmental regulations. Her expertise includes process analysis, water discharge calculations, compliance evaluations, wastewater infrastructure cost development, pollution prevention, and regulatory development.

Lori provides senior support across a variety of engineering and environmental analyses, drawing on her cross-cutting experience with multiple programs, media, pollutants, and industrial and municipal programs. She has managed and directed numerous projects and studies for EPA’s Office of Water across industries including chemical manufacturing, petroleum refining, oil and gas extraction, and metals processing. She has also supported EPA’s enforcement and chemical safety and pollution prevention programs.

Lori holds a B.S. in chemical engineering from Carnegie Mellon University and an M.S. in environmental engineering from Virginia Tech. She enjoys making frequent visits to her hometown of Pittsburgh and spending time with her young son.
