Description: The DNREC underground storage tank (UST) compliance program is responsible for ensuring the safe operation of over 400 federally regulated UST and 150 state regulated UST heating oil facilities in the state. The program oversees the installation, retrofitting, compliance and removal of underground storage tank systems to verify the work is completed properly and by qualified, trained, and certified individuals and companies. Underground storage tank systems which are subject to the requirements of the underground storage tank compliance program can be found at gas stations, manufacturing facilities, schools, and hospitals. Data is Underground_Storage_Tanks Enterprise Geodatabase View from the Delaware Environmental Navigator (DEN) database updated via UST-DE app.

Description: Certain by-products of wastewater treatment, known as biosolids, and non-hazardous residuals from wastewater treatment, can be used, under certain circumstances, in limited agricultural applications. These uses are governed by Parts III and V of the Guidance and Regulations Governing the Land Treatment of Wastes (7 DE Admin. Code 7103). The biosolids and residuals data shows the location of areas in Delaware where agricultural utilization permits have been issued to allow for the land application of biosolids and non-hazardous waste residuals. BiosolidsSewage sludges that are solid, semisolid, or liquid residues generated during primary, secondary, or advanced treatment of sanitary sewage. Treated sewage sludge that has undergone an approved process to reduce pathogens, a process to reduce the attractiveness of the material to disease carrying vectors (flies, birds, rodents), and that meets regulatory limits for certain pollutants are known as biosolids. Biosolids are typically used as a fertilizer or soil amendment or are disposed of in a landfill.EPA regulations (40 CFR Part 503) establish the minimum national standards for the use and disposal of biosolids. EPA’s standards are incorporated into Delaware regulations. The state’s rules include additional requirements and safeguards that are not required in EPA standards.Non-Hazardous Waste ResidualsNon-hazardous residual materials from waste treatment that do not contain a sanitary waste component can be permitted for agricultural use under Part V of the Guidance and Regulations Governing the Land Treatment of Wastes. These wastes must meet regulatory limits for certain pollutants and must be suitable for use as a fertilizer substitute or as a soil amendment.This layer includes land application sites where non-hazardous waste residuals disposal (were beneficially reused may be a better phrase to describe “disposal” if this description goes on a public server) via land application have been approved. For sites where beneficial reuse of wastewater via spray irrigation has been approved please see the Spray Irrigation layer.

Description: The Large Systems Branch reviews and approves spray irrigation wastewater systems and onsite wastewater treatment and disposal systems with daily flows greater than 2,500 gallons per day. It oversees Underground Injection Control (UIC) wells and other forms of wastewater treatment. The permits are broken up into two categories, Septic-UIC and Septic-NonUIC. It was created as a reference and aid to internal staff, partnered agencies and to be shared with the public. this data is also used as a screen in division wide permitting processes.Data is ENV_LargeSystems Enterprise Geodatabase Feature Class made available from DNREC's Enterprise Geodatabase.
