The following terms are used in the Bureau for Remediation and Redevelopment Tracking System (BRRTS) on the Web (BOTW).
| Activity Type |
Definition |
|---|
| |
Activity type divides the data in BRRTS into separate modules, or groups of activities, including:
- Abandoned Container (AC):
An abandoned container with potentially hazardous contents has been inspected and recovered. No known discharge to the environment has occurred. If the container discharged a hazardous substance, a spills activity will be created at this location (See SPILLS below). Abandoned container activities in BRRTS have an activity number prefix of "08."
- Legacy Sediment - Areas where historical discharges occurred to navigable waterways and the contamination is still causing adverse effects to the environment. These sites have no viable responsible party identified and are most often in designated Great Lakes Areas of Concern, but can be elsewhere. Legacy sediment activities in BRRTS have an activity number prefix of "11."
- Leaking Underground Storage Tank (LUST):
A LUST site has contaminated soil and/or groundwater with petroleum, which includes toxic and potentially cancer-causing substances. However, given time, petroleum contamination naturally breaks down in the environment (biodegradation). Some LUST sites may produce potentially explosive vapors. LUST activities in BRRTS have an activity number prefix of "03."
- Environmental Repair Program (ERP):
ERP sites are sites other than LUSTs that have contaminated soil and/or groundwater and are addressed under Wis. Stat. 292.31. Examples include industrial spills or releases that require long-term investigation, buried containers of hazardous substances or closed landfills that have caused contamination. The ERP module includes petroleum contamination from above-ground (but not from underground) storage tanks. ERP activities in BRRTS have an activity number prefix of "02."
- Spills:
A discharge of a hazardous substance that may adversely impact, or threaten to impact public health, welfare or the environment. Spills are usually cleaned up quickly. Spill activities in BRRTS have an activity number prefix of "04."
- General Property Information (GP):
This activity type consists of records of various milestones related to liability exemptions, liability clarifications, and cleanup agreements that have been approved by the DNR to clarify the legal status of the property. General Property activities in BRRTS have an activity number prefix of "07."
- Voluntary Party Liability Exemption (VPLE):
VPLE is an elective process in which a voluntary party conducts an environmental investigation and cleanup of an entire property and then receives limits on future liability for that contamination under Wis. Stat. § 292.15. An individual, business or unit of government can receive the liability exemption after a completed cleanup is approved. VPLE activities in BRRTS have an activity number prefix of "06."
- No Action Required by RR Program (NAR):
There was, or may have been, a discharge to the environment and, based on the known information, the DNR has determined that the responsible party does not need to undertake an investigation or cleanup in response to that discharge. NAR activities in BRRTS have an activity number prefix of "09."
- Materials Management:
Properties that received contaminated materials from a response action site. The materials will be managed on the property in compliance with Wis. Admin. Code ch. NR 718. Materials management activities in BRRTS have an activity number prefix of "15."
- Facility wide:
This is an umbrella activity of a subset of activities at a facility that are part of the same negotiated agreement. Generally, these activity types are large sites with continuing operations that have smaller releases over time. There may also be some activities at the same location that should not be part of the Facility-wide Activity Type because they are not covered by the negotiated agreement. Facility-wide activities in BRRTS have an activity number prefix of "16."
- Off-Sites:
This activity type consists of properties that were affected by contamination from another property. Information about the contamination may be found under the activity for the source property. These types of activities in BRRTS have an activity number prefix of "13."
