12/2012 - Current

Independent Consultant on Environmental Issues

Subcontract: Council Fire; Chesapeake Bay Accounting for Growth project


1/2003 – 7/1/2012 (semi-retirement)

Director, Science Services Administration (Acting 1/03-9/03 at Director’s pay) - Responsible for leadership and oversight of a major unit of the Maryland Department of the Environment; up to 110 staff and $15 million budget for a broad portfolio of technical, scientific and outreach activities. This position reports to the Secretary of the Environment and supports the Department’s mission and vision to protect the environment and foster smart growth, economic development, and healthy and safe communities. Required tasks include managing large, complex projects in support of permitting and compliance activities, environmental health and environmental assessment. Examples include Chesapeake Bay Restoration (TMDL and Watershed Implementation Plans), water quality standards, biological and chemical monitoring, shellfish harvesting classifications, field operations, local pollution limits (TMDLs) and environmental health. The Director must establish a strategic vision for the Administration and proactively recognize the need for change. Change is a constant in this position, and is driven by intrinsic (e.g., budget) and extrinsic (e.g., federal regulations) factors and must be successfully managed in a complex environment reconciling environmental and economic interests. Delegated appointing authority with responsibility for personnel actions, budgetary decisions and legislative duties in addition to supervising the duties of the Deputy specified below. Notable accomplishments: first external on-line system in the Department for regulated entities to enter data (Community-Right-to-Know) in regulatory database, expanded and refined fish consumption advisories, drafted and managed the promulgation for Outstanding National Resource Water designation, antidegradation implementation, biocriteria regulations, and hazardous material security regulations.  Maintained TMDL production despite significant budget reductions; over 350 TMDLs approved. Timely completion of draft and final statewide Watershed Implementation Plan in support of the Chesapeake Bay TMDL. Member Chesapeake Bay Water Quality Steering Committee; Implementation Committee, chair Toxics Committee; chaired Use Attainability Workgroup.

Supervisor: Director, Technical and Regulatory Services.

Under general supervision of Administration Director shared management of units conducting field operations (emergency response and monitoring), water quality modeling, environmental planning and assessment, Departmental information technology staff, and fiscal and personnel services for the Administration. These units in total contained about 140 staff with an $18 million budget. Responsibilities emphasize technical policy especially for water quality, public health protection, risk assessment, TMDLs, 303(d) list, monitoring and assessment, and aspects of budget, legislation, and internal and external coordination. Accepted rotating chairmanship of Budget, Planning and Operational Performance Committee composed of Agency Deputies and fiscal and planning officers (10/02 to 4/03). Frequently lead diverse groups to common goals as chair or staff of workgroups, or as a member of ad hoc panels; commonly resolved conflicts with individuals with respect to administration's programs. Most of these responsibilities require extensive coordination and leadership within the Department, and with other State and federal agencies, local governments, non-governmental organizations, and private citizens. Strong management and communication skills and technical knowledge are required; an understanding of larger policy implications is essential.
