NR 216.21(3)(a)(a) Discharges composed entirely of storm water are not storm water discharges associated with industrial activity if there is no exposure of industrial materials and activities to storm water, and the discharger satisfies the conditions in pars. (b) to (e). “No exposure" means that all industrial materials and activities are protected by a storm resistant shelter to prevent exposure to storm water. Industrial materials or activities include material handling equipment or activities, industrial machinery, raw materials, intermediate products, by-products, final products or waste products. Material handling activities include the storage, loading and unloading, transportation or conveyance of any raw material, intermediate product, final product or waste product.
NR 216.21(3)(b) (b) Qualification. To qualify for this exclusion, the operator of the discharge shall do all of the following:
NR 216.21(3)(b)1. 1. Provide a storm resistant shelter to protect industrial materials and activities from exposure to storm water.
NR 216.21(3)(b)2. 2. Complete and sign, in accordance with s. NR 216.22 (7), a certification that there are no discharges of storm water contaminated by exposure to industrial materials and activities from the entire facility, except as provided in par. (c).

NR 216.21 Note Note: The department's no exposure certification form, Form 3400-188, requests necessary information to be consistent with federal requirements and U.S. EPA NPDES Form 3510-11, including the latitude and longitude of the facility. U.S. EPA has published a guidance document entitled Guidance Manual for Conditional Exclusion from Storm Water Permitting Based On "No Exposure" of Industrial Activities to Storm Water, EPA 833-B-00-001, dated June 2000. This guidance is available from the U.S. EPA website at The department no exposure certification form is available from the department website at

NR 216.21(3)(b)5. 5. Allow the department to inspect the facility to determine compliance with the “no exposure" conditions.
NR 216.21(3)(b)6. 6. Allow the department to make any “no exposure" inspection reports available to the public upon request.

NR 216.21(3)(c) (c) Industrial materials and activities not requiring storm resistant shelter. To qualify for this exclusion, storm resistant shelter is not required for any of the following:
NR 216.21(3)(c)1. 1. Drums, barrels, tanks and similar containers that are tightly sealed, provided those containers are not deteriorated and do not leak. “Sealed" means banded or otherwise secured and without operational taps or valves.
NR 216.21(3)(c)2. 2. Adequately maintained vehicles used in material handling.
NR 216.21(3)(c)3. 3. Final products, other than products that would be mobilized in storm water such as rock salt.
NR 216.21(3)(d) (d) Limitations.
NR 216.21(3)(d)1.1. This conditional exclusion from the requirement to obtain a permit under this subchapter is available on a facility-wide basis only, not for individual outfalls. If a facility has some discharges of storm water that would otherwise be “no exposure" discharges, individual permit requirements may be adjusted by the department accordingly.
NR 216.21(3)(d)2. 2. If circumstances change and industrial materials or activities become exposed to storm water, the conditions for this exclusion no longer apply. The discharge then becomes subject to enforcement as an unpermitted discharge. Any conditionally exempt discharger who anticipates changes in circumstances shall submit a notice of intent to the department 14 or more working days prior to the change of circumstances and in accordance with s. NR 216.22.
NR 216.21 Note Note: A facility that has claimed a condition of “no exposure" should routinely inspect its facility to verify that it continues to operate in a condition of “no exposure."
NR 216.21(3)(d)3. 3. Notwithstanding the provisions of this subsection, the department retains the authority to require permit authorization and deny this exclusion upon making a determination that the discharge causes, has a reasonable potential to cause, or contributes to an exceedence of an applicable water quality standard, including designated uses.
NR 216.21(3)(e) (e) Certification. The “no exposure" certification shall include all of the following information, at a minimum, to aid the department in determining if the facility qualifies for the “no exposure" exclusion:
NR 216.21(3)(e)1. 1. The legal name, address and phone number of the discharger.
NR 216.21(3)(e)2. 2. The facility name, address and the county name where the facility is located.
NR 216.21(3)(e)3. 3. The certification shall indicate that none of the following materials or activities are, or will be in the foreseeable future, exposed to precipitation:
NR 216.21(3)(e)3.a. a. Using, storing or cleaning industrial machinery or equipment, and areas where residuals from using, storing or cleaning industrial machinery or equipment remain and are exposed to storm water.
NR 216.21(3)(e)3.b. b. Materials or residuals on the ground or in storm water inlets from spills and leaks.
NR 216.21(3)(e)3.c. c. Materials or products from past industrial activity.
NR 216.21(3)(e)3.d. d. Material handling equipment, except adequately maintained vehicles.

NR 216.22 (7): “I certify under penalty of law that I have read and understand the eligibility requirements for claiming a condition of “no exposure" and obtaining an exclusion from permitting requirements under subch. II of ch. NR 216; and that there are no discharges of storm water contaminated by exposure to industrial activities or materials from the industrial facility identified in this document, except as allowed under s.
