This series specification describes three Environmental Scientist and three Environmental Program Manager classifications used to perform a broad range of staff, supervisor, and management work concerning present and future environmental, environmental health, and natural resource management issues related to protecting California's natural resources, agricultural productivity, and public health. Incumbents give presentations; prepare environmental permitting packages, regulatory permits, and other environmental documents; implement enforcement of various environmental and environmental health-related laws and regulations; and conduct natural resource management and environmental protection, planning, and implementation activities. Incumbents apply scientific methods and principles in the identification, research, and solution of problems in the areas of biodiversity planning, environmental monitoring, water resources development, water conservation, water recycling, waste classification, and illegal discharge of waste (including solid and hazardous waste) to the lands and waters of California, toxic and hazardous materials management, point and nonpoint source pollution, natural area management, habitat protection and restoration, wetland restoration, river greenways, riparian habitat, land and water use, agricultural return flows, agricultural productivity, timber harvesting, streambed alterations, and watershed evaluation. Incumbents analyze and evaluate available data on the effects of air and water pollutants, waste management, prevention and recycling, water diversions, and water use on human health, vegetation, fish, wildlife, water supplies, potential land uses, and other aspects of the environment; prepare and review environmental impact reports and other documents to determine the effects of proposed activities on environmental health and all areas of the environment; coordinate environmental programs related to air, water and agricultural development, pollution, waste management and control, and other environmental and environmental health programs with other public and private agencies; develop regulatory measures and implement enforcement of environmental standards; manage and oversee site cleanup and emergency response efforts; develop recommendations regarding environmental programs as these may be affected by scientific findings; prepare and edit scientific papers for publication; research and develop innovative programs to address emerging problems; develop scientific methodologies, develop and assess alternatives for mitigation of the hazards to the public and environment; conduct or participate in remedial investigations, feasibility studies, and remedial action plans; review facility environmental practices; consult with and advise other agencies and institutions engaged in related environmental analysis, management, planning, regulation, investigation, and research; meet and confer with individuals and groups to obtain compliance with laws and regulations concerning environmental requirements of California and Federal governments; provide training; evaluate and certify local enforcement agencies; develop and/or analyze legislation, regulations, plans, policies, procedures, alternative technologies, practices, criteria, and guidelines; inspect permitted facilities, regulated activities, and contaminated or environmentally sensitive sites; participate in hearings and field investigations as a staff expert for environmental matters; and prepare reports and correspondence. On occasion, incumbents may perform environmental analysis in a laboratory setting.
