An Overview and History

ASTSWMO was incorporated in 1974, and has maintained a full time office in Washington, DC, since 1980. The Association holds two general membership meetings each year, and a number of specialized roundtables, workshops or conferences for specific program areas of high interest. The Association also provides a steady flow of services and information to our members along program specific lines throughout the year. We work closely with the U.S. Environmental Protection Agency to ensure that our members are aware of the most current developments related to their programs and coordinate the work of our State regulators with that of their federal counterparts. The Association also represents the interests of our members in Washington, DC. While no single entity can speak for all State waste programs, the capability of consolidating similar views and ensuring that State managers have the opportunity to speak in unison on important waste management issues assists their ability to influence national decision-making.

ASTSWMO's most important role is to assist States in learning from and working with other State peers. Within the Association it is an axiom that States learn best from other States in matters of program implementation, and ASTSWMO's collective efforts are all focused on making that happen.

A Historical Timeline


ASTSWMO was founded on October 22 in Georgia and operated as technical advisers to the National Governors Association's Waste Management Subcommittee until 1980.  Moses McCall (GA) was President of ASTSWMO during that time, during which no Washington office existed.


Forty State members paid their dues.  ASTSWMO held its Annual Meeting in Atlanta in conjunction with the National Solid Waste Management Association (NSWMA)/U.S. Environmental Protection Agency (EPA) Conference on Waste Management and Resource Recovery.  Nineteen State officials attended the half-day session.  The treasurer's report indicated an unofficial fund balance of $375.00.


Jack Carmichael (TX), Norm Nosenchuck (NY), Jack McMillan (MS), and a few other State waste managers met in a hotel room in Kansas City to formulate the revitalization of the Association.  A grant proposal was written to support Washington, DC, office activities...


...and EPA awarded ASTSWMO $189,580 for one year on May 27.

Jacki Rams was hired as a staff coordinator on June 23.  The Washington, DC, office officially opened on June 30 in the Hall of the States. 

In the fall of 1980, a two-year grant was awarded to ASTSWMO by the Department of Commerce (DOC) to perform a State measurement needs study, and evaluate an econometric model being developed for regional resource recovery facilities.  Barbara Simcoe was hired in December 1980 to assist Ms. Rams in this effort. 


David Duncan was hired as Executive Director in February.  The EPA grant was extended and supplemented by $115,500.

Under the DOC grant, ASTSWMO published its eight-volume State Measurement Needs Study, which was based on site visits to six States to look at RCRA laboratory sampling procedures and needs. 


Sue Moreland was hired as Executive Director in February.  ASTSWMO's funding situation was unstable, despite the funding from EPA.  The DOC grant money was depleted, and staff was reduced from five to three.

In FY1983, ASTSWMO's Board of Directors decided to try to bring in extra funding support from State fee assessments, hoping to begin weaning the Association from total federal support and build a financial cushion in case the federal grant funding ceased.  ASTSWMO collected $70,000 from 23 States in 1983.


Kerry Callahan joined the ASTSWMO staff in March.

In May, ASTSWMO's Board, in its first attempt to deal with strategic planning needs, identified Association goals for future planning purposes: to become financially independent, to provide membership targeted services, to increase membership, and to increase the Association's impact on federal legislation.

ASTSWMO conducted its Annual Meeting and tenth anniversary celebration in Orlando, FL.


On May 1, Tom Kennedy joined the staff as the Executive Director to steer the Association on a more fiscally balanced course. 


Katrina Taylor joined the ASTSWMO staff in July as the new Training Associate.

In September, in Monterey, CA, the Board of Directors held its first intensive meeting to strategically plan for ASTSWMO's future, to develop an Association mission statement, and to identify ambitious goals and objectives.

In October, ASTSWMO held its Annual Meeting in San Antonio, TX, where members elected the Association's first female Vice President, Cheryl Koshuta (ID). State member attendance at the meeting exceeded 100 people for the first time.


After two years of consideration, the Association finally adopted a new logo, which portrays ASTSWMO as “slanted toward the future.”


Nicole Malloy became ASTSWMO's Office Manager in August.


The Board of Directors approved a merger of ASTSWMO's District of Columbia and Georgia corporations, adjusted the State fee assessment tiers, and continued with its strategic planning process.  The Board also discussed and approved switching the locations of our membership meetings; henceforth, Annual Meetings would be held in the Washington, DC, area and Mid-Year Meetings would be held in the State or EPA Region of the Association’s Past President.


The Board completed work on a co-implementation plan to answer State environmental commissioners' procedural and substantive questions about the respective roles of the State players involved in the regulatory process.  The plan was presented to the commissioners' newly formed organization, the Environmental Council of the States (ECOS), and was heartily endorsed.

ASTSWMO’s 1994 Annual Meeting in Arlington, VA, marked the 20th anniversary of the Association's formation.


Steve Crimaudo was hired as ASTSWMO’s Tanks Staff Associate in January.


The ASTSWMO Board formally approved a new five-tier fee assessment structure for the Association based on State population. It was phased in over a two-year period beginning in FY1997.

The Annual Meeting was held in Atlanta, GA, in October to celebrate the Association’s 25th anniversary in the State where the Association was founded.


Kris Swanson joined ASTSWMO as the CERCLA Staff Associate in October 2001.

ASTSWMO updated its Strategic Plan, which set out ASTSWMO’s vision and strategic directions to accomplish ASTSWMO’s mission.  The strategic directions included program development and support; national policy development; accomplishing near-term opportunities in information management, technical assistance, resources, environmental indicators; reviewing and reaffirming ASTSWMO’s structure; and maintaining focus on the strategic directions.


The Association’s 2004 Annual Meeting in Arlington, VA, marked its 30th anniversary.

In December, Jennifer Patterson was hired as the CERCLA and Brownfields Staff Associate.


In July the Association revised its Strategic Plan, which continued to: support enhancements and innovation in State and Territorial waste prevention, management, and cleanup programs; and affect national waste prevention, management, and cleanup program direction and policy. The plan also anticipated a stronger leadership role by the States and Territories in formulating issues, encouraging innovative approaches and solutions, and enabling a new generation of State and Territorial program managers.


Executive Director Tom Kennedy and Deputy Director Barbara Simcoe announced their plans for retirement from the Association. 


In April, Dania E. Rodriguez was promoted to Deputy Executive Director.

In May, Julius Shapiro was hired as a Program Staff Associate. He assumed the duties of Tanks Staff Associate in 2008.

In May, Allison Goldberg was hired as the Information Staff Associate.

In July, Charles Reyes was hired as the Federal Facilities Staff Associate.

In December 2008, Sam Puffenbarger was hired as the CERCLA and Brownfields Staff Associate.


The Association celebrated 35 years.  ASTSWMO reviewed its existing Strategic Plan. A revised mission statement cemented ASTSWMO’s commitment to the evolution of State waste and cleanup programs to include consideration of environmental sustainability and materials management.  The plan also included five principles that will guide the Association’s actions for three to five years.  For the most part, these principles are not new to the organization; including them in the Strategic Plan highlights their importance to ASTSWMO’s continued success.  Like previous strategic plans, the 2009 Strategic Plan used strategic focus areas to organize and emphasize key Association activities.

A member from Guam joined the Board of Directors as the Region 9 Representative, which was the first time one of the Territories has served on the Board.
