Carson Bowler


Environmental and natural resource issues have been at the core of Carson Bowler’s practice for more than 20 years. Carson was trained as a litigator, but now also handles many transactional matters that involve cleaning up contaminated properties and/or buying and selling such properties. Carson’s litigation experience helps him understand risk in transactional matters, and his transaction experience helps him frame the strengths and weaknesses of a case in court.

On the transaction side, Carson has worked on dozens of deals requiring due diligence review, indemnities, pollution insurance provisions, and other aspects of real estate transactions for buyers, sellers, landlords, and tenants of contaminated properties. Carson has been involved with transacting or cleaning up sites formerly and currently used as gas stations, dry cleaners, forest product mills, manufacturing facilities, auto wrecking yards, mines, and bulk fueling facilities. He is also familiar with operations and risks associated with forestry and agricultural land and has negotiated many Prospective Purchaser Agreements to reduce liability exposure for properties with environmental risks.

Carson also helps clients with stormwater permitting and compliance, hazardous and solid waste management, project development, water quality and quantity disputes, wetlands issues, and locating environmental insurance coverage.

Carson still has an active litigation practice, both in court and in administrative settings, and will try a case if that is the best course of action. But he has also negotiated resolution of many disputes by way of settlements, consent judgments/orders, and other agreements with state and federal administrative agencies.

In addition to the above, Carson advises a few fantastic companies on day-to-day decision-making, including managing risks and liabilities. Carson refers to himself in the third person in this bio, but not when he talks to you.
