Assistance is provided to other agencies (primarily the Lincoln Fire Department, Lincoln Police Department, Lancaster County Sheriff's Office, and State Patrol) to stabilize the incident and assure proper clean-up.

Land Use Plan and Subdivision Review provides the following assurances: newly proposed land uses do not pose health or environmental risks, adequate water or acceptable quality will be available for the proposed use of the property, and that adequate on-site wastewater sewage disposal is planned. Review all new plats, subdivisions, change of zones, special permits, and community unit plans with regard to groundwater quality and quantity, soil types and implications for on-site wastewater treatment systems. Other environmental health concerns including proximity of residential uses or schools, childcare or assisted living facilities to industrially zoned areas and hazardous materials risks are addressed. Community wastewater treatment systems are also reviewed in conjunction with the Nebraska Department of Environmental Quality (NDEQ), and specific recommendations are made for approval or disapproval.
