In addition, he also oversees the State’s Brownfields Redevelopment and Voluntary Cleanup Program.
He began his career with ADEM in 1993 as a staff engineer working in RCRA permitting, corrective action, and CERCLA remediation. He was assigned to some of Alabama’s most complex waste and remediation projects including permitting the Chemical Waste Management TSD facility, still the country’s largest hazardous waste disposal facility, and the Anniston, Alabama PCB and Lead remediation sites. Chip spearheaded ADEM’s initial efforts to develop a comprehensive environmental investigation, remediation, and risk management guidance. Over his 24-year career with ADEM, he has held several management positions in both waste and water programs focusing on RCRA, CERCLA, Brownfields, NPDES, Mining, and Stormwater Management. Chip is one of the founding committee members and a current board member of the Alabama Brownfields Association.
Chip has been active in ASTSWMO since the late 1990’s. He participated along with numerous other States in EPA’s early efforts to establish the 2020 Corrective Action Initiative. He represented ASTSWMO on the RCRAInfo Version 4 design team. Chip has been member of the Hazardous Waste Subcommittee’s Corrective and Permitting Task Force and currently chairs the CERCLA and Brownfields Subcommitee’s Sediments Focus Group.
Chip holds a B.S. in Agricultural Engineering from Auburn University and an M.B.A. from Auburn University Montgomery. He lives in Wetumpka, Alabama with his wife of 23 years, Julie, who is a public high school teacher. They have two incredibly talented and busy children. Their son Ryan is a sophomore at Samford University on a baseball scholarship. Their beautiful daughter Juliana is a high school junior, former State champion gymnast, varsity cross-country runner, and soccer player.
Conchita San Nicolas Taitano has been the ASTSWMO voting member for Guam for over 20 years and an active member for the last decade. She served in ASTSWMO as a Task Force member on one of the past Hazardous Waste Task Forces, the ASTSWMO Region 9 Board Representative for four years, and currently is the Region 9 member on the ASTSWMO Sustainable Materials Management Task Force.
Conchita has been with the Guam Environmental Protection Agency (Guam EPA) for 29 years and working as the Air and Land Division Administrator for over 22 years overseeing the Air Program, Pesticides Program, Hazardous Waste Program (which includes RCRA C, RCRA I and SPCC), and the Solid Waste Program.

In addition, she studied Environment and Sustainable Development from the United Nations University in Tokyo, Japan. She also studied Environmental Policy Making from the UNESCO Water Institute in the Delft, Netherlands.
Prior to her career in the environment, Conchita was a high school math and science teacher. She is a past president for Soroptimist International of the Marianas and currently a member of the State Rehabilitation Council as a disability advocacy representative.

As the Director for the New Jersey Department of Environmental Protection’s (NJ DEP) Division of Remediation Management, Ken is responsible for all site remediation activities in New Jersey, including those performed by Licensed Site Remediation Professionals on behalf of responsible parties and brownfield developers; CERCLA; RCRA corrective action; federal facilities and NJDEP-funded response actions.
Ken’s involvement with ASTSWMO began in the late 1980s when he was invited to join the CERCLA Site Evaluation Focus Group, which he later chaired for several years before serving as Chair of the CERCLA & Brownfields Subcommittee. Prior to serving as Vice President he served two consecutive three-year terms as Region 2 Representative on the Board of Directors and member of the Finance Committee. He also serves on the ad-hoc Poly- and Perfluoroalkyl Substances (PFAS) Workgroup.
Ken is a 1981 graduate of Seton Hall University with a B.S. in Biology. He began his career with the New Jersey Department of Environmental Protection in 1985 as a field investigator, evaluating contaminated sites for inclusion on the National Priorities List. He has served in various managerial roles within the NJDEP, including Brownfield Administrator, where he implemented a number of innovative approaches for brownfields remediation and redevelopment, including New Jersey’s Brownfield Development Area (BDA) initiative.
Most recently, Ken was instrumental in the New Jersey’s transition from a “traditional” remediation oversight program to one employing Licensed Site Remediation Professionals, or LSRPs, who are retained by remediating parties to perform remediation activities in accordance with NJDEP statutes, regulations and guidance, but without specific direction from, or the day-to-day involvement of, NJDEP regulators.
Ken is a life-long resident of New Jersey, currently residing in Toms River, New Jersey, with his wife, Karen, a Bureau Chief for NJDEP’s Bureau of recycling and Hazardous Waste. Together they enjoy sailing, fishing and crabbing, and most other water-related activities. They are the proud parents of two amazing young men, Alex, an officer in the US Coast Guard, and Adam, currently employed with a private environmental engineering firm.
Tim Ratsep is the Administrator of the Delaware Department of Natural Resources and Environmental Control (DE-DNREC) Site Investigation and Restoration Section. He is responsible for the Superfund, Brownfields, Voluntary Cleanup, Federal Facilitates, and the Pre-Remedial programs within the State of Delaware. As part of these responsibilities, Tim oversees the State Hazardous Substance Cleanup Act fund, which receives millions of dollars in State funding allocated to remedial programs. Although, historically State allocations have been substantial to address its liabilities; due to funding reallocations Tim has been working with limited funds to balance priorities such as emergency response and unanticipated groundwater contamination relating to PFAS.
Prior to joining the State in 2005, Tim worked in the private sector on RCRA and CERCLA facilities throughout the United States. During his tenure with the State, Tim has initiated Lean management principals within the Section. He has been recognized in two Governors Team Excellence projects that utilized limited resources to meet the Department objectives. These projects resulted in tens of millions in savings for the State. Tim became active in ASTWMO in 2009 and joined the Remedial Action Focus group in 2013 working to become Vice-Chair and this past year became Chair.
Tim received a Bachelor of Science in Environmental Soil Science from the University of Delaware and has a Master’s of Business Administration from Wilmington University. He is married to his grade school sweetheart and has two wonderful children.
Members of the Board other than officers are elected by a State regional caucus and consist of one representative from each of the 10 EPA Regions. Each Board member serves an initial 3-year term and may serve a maximum of two full consecutive 3-year terms with the consent of their regional caucus. Board members are vested with the authority to carry out the affairs of the association and to exercise leadership in raising and exploring policy issues of potential concern to the membership.
