Peter Niemiec delivers the experience, judgment and business sense of over thirty years to the practice of environmental law and real estate transactions.

Peter began his legal career in 1976 as a litigation associate at a major Los Angeles law firm. In 1980, he joined the United States Environmental Protection Agency, where he led the development of rules and policies for the enforcement of pollution control laws. His government experience continued as a Deputy Attorney General for the State of Indiana, where he had sole responsibility for civil enforcement matters involving air, water, and soil pollution, defended state permit decisions, and litigated cost recovery and cleanup matters.

Since his return to Los Angeles in 1986, he has served as in-house counsel with major corporations (Southern California Gas Company and Unocal), as well as the sole environmental lawyer for a leading Los Angeles boutique real estate law firm. In these positions, he successfully handled investigations and enforcement actions involving pollution control laws, structured deals for clients purchasing and selling properties with contamination issues, brought and defended cost recovery actions, represented clients in Superfund matters, and successfully appealed agency cleanup decisions. He has obtained coverage for pollution problems under clients’ old insurance policies, as well as negotiated environmental insurance policies that facilitated deals at “brownfields” sites.

The Law Office of Peter Niemiec opened in 2001. Peter continues to handle a wide variety of commercial property transactions and pollution-related issues. He structures deals for clients purchasing, selling and leasing commercial and industrial properties, especially properties with contamination issues, and handles commercial and industrial leases involving a broad range of facilities, including, office, retail and industrial space, as well as ground leases for service station and other retail facilities. He advises clients on contaminated property cleanups, represents individuals identified as “potentially responsible parties” in connection with area-wide Superfund sites, and handles the defense of enforcement actions, underground tank problems, asbestos issues, and Proposition 65 compliance.
