HVAC refrigerants and non-functioning lights are stored by the Public Works and Transportation Department .

Removal of these wastes typically occurs on a quarterly schedule .

Pesticide , Herbicide , and Fertilizer Application
Municipal Uses Management Program The Parks and Recreation Department applies the majority of the fertilizers , pesticides , and herbicides on cityowned property . The department maintains a staff of licensed applicators to treat parkland and other City grounds as needed , including weed control in rights-of-way and medians . These applicators ensure full compliance with federal and state regulations when applying chemicals to public lands . There have been no changes to the program during this reporting period .
The City of Arlington continues to follow a “ least toxic alternative ” approach to pesticide management using Integrated Pest Management ( IPM ) practices . The IPM philosophy uses a coordinated strategy to identify when and where pest suppression treatment is needed , and what strategy and mix of measures should be used that are effective , but also low in cost and environmentally sound . IPM measures include structural , cultural , biological and chemical control in combinations which offer efficient and safe means of keeping pests at tolerable levels .
The following departments have limited uses of pesticides , herbicides and fertilizers for targeted needs such as controlling vegetation growing in pavement joints at the airport and treating for mosquitoes : Public Works and Transportation , Code Compliance Services , Environmental Health , Fire , Water Utilities , and Facility Services . Applications by these departments are accomplished through a combination of their own staff , Parks and Recreation Department ’ s staff , and contractors . All Federal and State regulations are followed , and licensed applicators are used as required .
