NR 706.03 Definitions. In this chapter:
NR 706.03(2)
(2) “Fertilizer" has the meaning specified in s.
94.64 (1) (e), Stats., except that it does not include nitrates or other forms of nitrogen found in the environment that cannot be attributed to a discharge.
NR 706.03 Note
Note: Section
94.64 (1) (e), Stats., defines “fertilizer" to mean “any substance, containing one or more plant nutrients, which is used for its plant nutrient content and which is designed for use or claimed to have value in promoting plant growth, except unmanipulated animal or vegetable manures, marl, liming material, sewage sludge other than finished sewage sludge products, and wood ashes. `Fertilizer' includes fertilizer materials, mixed fertilizers, custom mixed fertilizers, nonagricultural fertilizers and all other fertilizers or mixtures of fertilizers, regardless of type or form."
NR 706.03(4)
(4) “Impervious" means incapable of being penetrated by a discharged substance.
NR 706.03 Note
Note: Asphalt and concrete, if intact and undamaged, are considered impervious surfaces. However, if hazardous substances are capable of penetrating asphalt or concrete due to cracks or holes, or repeated discharges, the surface would not be considered impervious.
NR 706.03(5)
(5) “Nonhousehold pesticide" has the meaning specified in s.
94.681 (1) (c), Stats., except that it does not include pentachlorophenol, inorganic arsenical wood preservatives and coal tar creosote.
NR 706.03 Note
Note: Section
94.681 (1) (c), Stats., defines “nonhousehold pesticide" as “a pesticide that is not a household pesticide or an industrial pesticide." “Household pesticide" is defined in s.
94.681 (1) (a), Stats.
NR 706.03 Note
Note: Section
94.67 (25), Stats., defines “pesticide" to mean “any substance or mixture of substances labeled or designed or intended for use in preventing, destroying, repelling or mitigating any pest, or as a plant regulator, defoliant or desiccant."
NR 706.03(7)
(7) “Petroleum product" means any refined petroleum based substance or blend intended for use as motor fuel, turbine fuel, heating fuel, a lubricant, a coolant, or for machine cutting.

NR 706.05
NR 706.05 General requirements for responsible parties. NR 706.05(1)(a)
(a) Unless the discharge is specifically exempted under s.
NR 706.07, persons who cause the discharge to the environment of a hazardous substance or who possess or control a hazardous substance which is discharged to the environment shall immediately notify the department of the discharge. Discharges to the environment may include recent discharges, historic discharges, and discharges caused by the long-term application of a substance. A hazardous substance that is “discharged" into a secondary containment structure, that is completely contained and can be recovered with no discharge to the environment, is not subject to the discharge notification requirements in s.
292.11 (2), Stats.
NR 706.05 Note
Note: The department believes that the dictionary definition of “immediately", i.e. “occurring at once; next in line," does not lend itself to quantification. An across–the–board time–period can't be specified. In uncomplicated hazardous substance discharge situations, responsible parties are expected to provide notice to the department within a matter of a few minutes after they learned of the discharge. In other situations, especially where emergency action of some kind is being taken by the responsible party or where the responsible party does not have access to a telephone, notification may not be possible for several hours, but would still be considered “immediate" if promptly given.
NR 706.05(1)(b)
(b) Hazardous substance discharges shall be immediately reported to the department by telephoning the department–designated 24–hour hotline telephone number. The department may allow alternate notification procedures on a case-by-case basis.
NR 706.05 Note
Note: Use of the department-designated 24-hour hotline is for notification of spills. The hotline operated by the division of emergency management in cooperation with the department can be reached at 1–800–943–0003.
NR 706.05 Note
Note: If a notification of a natural gas discharge is made to the National Response Center in compliance with
49 C.F.R. § 191.5 (Code of Federal Regulations) it is not necessary to report under this chapter. The department does not require natural gas discharges which are not reportable to the National Response Center to be reported to the Department. The department will receive natural gas discharge notifications through the National Response Center.
NR 706.05(1)(bm)
(bm) Hazardous substance discharges discovered through soil, water or other analyses may be reported by telefaxing a completed discharge notification form provided by the department, or by alternate notification procedures approved by the department. Laboratory results shall be included with the completed discharge notification form.
NR 706.05 Note
Note: Use of the discharge notification form is intended only for notification of discharges typically found through tank closure assessment, phase II environmental assessments, or by other discoveries through soil, water or other media analysis. The discharge notification form can be obtained and submitted through the RR Program Submittal Portal at the following web address:
https://dnr.wisconsin.gov/topic/Brownfields/Submittal.html.
NR 706.05(1)(c)

302 are more restrictive, in which case the values in
40 CFR part 117 or
302 apply.
NR 706.07 Note
Note: Notification requirements under this rule may not meet the obligations for responsible parties to report hazardous substance releases to the federal government. Questions on federal requirements should be directed to the US EPA Superfund hotline at 1-800-535-0202.
NR 706.07(2)(b)
(b) Whenever, in light of site-specific conditions, any of the following criteria apply, hazardous substance discharges which would otherwise be exempt from notification under par.

NR 706.07(2)(b)4.
4. The discharged substance presents or threatens to present a fire or explosion hazard or other safety hazards, such as slippery conditions on a roadway.
NR 706.07 Note
Note: In determining whether a threat exists under subd. 1., 2., 3., or 4., the standard of conduct to which the responsible party must conform is that of a reasonable person under the site-specific circumstances.
NR 706.07(3)
(3)
Exemption from penalties. Law enforcement officers or members of fire departments using hazardous substances in carrying out their responsibility to protect public health, safety or welfare are exempted from the penalty requirements of s.
