Calibration. At least once every 12 months according to manufacturer's recommendations.
Control of adverse effects generally. The permittee shall take necessary steps prescribed by the Town to control adverse effects from his/her activity.
General requirements. Blasting shall be conducted so as to prevent injury and unreasonable annoyance to persons and damage to public or private property outside the permitted explosives use area.
Limits. Airblast shall not exceed the maximum limits listed in Table A-1 at the location of any dwelling, public building, place of employment, school, church or community or institutional building outside and beyond the permitted explosives use area. Notwithstanding this general requirement, an annual permit holder subject to this limitation may exceed the limitation on up to 5% of the blasts it initiates during the period from January 1 to December 31 without violating this chapter, provided that the airblast produced by such blasts does not exceed the limitations on airblast imposed by the Wisconsin Department of Safety and Professional Services in § SPS 307.44(3), Wis. Adm. Code, as amended from time to time.
Lower Frequency Limit of Measuring System
2 or lower - flat response
6 or lower - flat response
The permittee shall monitor all blasts at the closest location to the blast of any dwelling, public building, place of employment, school, church or community or institutional building outside and beyond the permitted explosives use area; provided, however, that the permittee may monitor, at another location approximately the same distance from the blast site, if the permittee is unable to obtain permission to conduct the monitoring from the owner of the preferred location. The Town Board or its designee may, at its discretion, require the relocation of monitoring equipment to a more suitable site and/or may conduct independent airblast monitoring to spot check data supplied by the permittee. If independent monitoring by the Town after hearing discloses that this chapter was violated by the permittee, then in that event the permittee shall pay the reasonable costs incurred by the Town for the independent monitoring. Upon receiving and approving billings for such expenses, the Town shall cause notice of the expenses to be mailed to the permittee, who shall reimburse the Town for such expenses within 30 days after receipt of such notice.
The measuring equipment used shall have an upper-end flat-frequency response of at least 200 Hz.
All measuring equipment during monitoring shall be spiked to the ground or sandbagged.
Flyrock. Flyrock produced as a result of explosives use shall be totally contained within the permitted explosives use area.
The maximum ground vibration at the location of any dwelling, public building, place of employment, school, church or community or institutional building outside or beyond the permitted explosives use area shall have a maximum peak-particle-velocity limit as provided by the Department, the scaled-distance equation provided by the Department, or the blasting level chart provided by the Department, whichever is applicable hereunder.
All structures in the vicinity of the permitted explosives use area not listed in Subsection G(1), such as water towers, pipelines and other utilities, tunnels, dams, impoundments and underground mines, shall be protected from damage by establishment by the permit holder of a maximum allowable limit on the ground vibration. The permit holder shall establish the limit after consulting with the owner of the structure.
The Town Board, in its discretion, may conduct independent seismic blast monitoring to spot check data supplied by the permit holder. If the independent monitoring was done after good cause was shown therefor and after the permittee was given notice and an opportunity to be heard on the matter, the permittee shall be liable to the Town for all expenses incurred by the Town as a result of such independent monitoring. Upon receiving and approving billings for such expenses, the Town shall cause notice of the expenses to be mailed to the permittee, who shall reimburse the Town for such expenses within 30 days after receipt of such notice.
The Town Board, upon good cause shown and after giving the permittee notice and an opportunity to be heard, may request analysis of records and data for any or all blasts which occurred within the permitted explosives use area.
Each explosives use permit application and all reapplications shall include the names and addresses of all residents or owners of dwelling or other structures located within an area affected by the permitted explosives use. The affected areas shall be determined based on the maximum pounds of explosives per eight MS delay from the previous three years' high. This calculation's square root times 100 shall determine the affected area in feet. This calculation shall be the maximum distance from the boundary of the quarry where a preblast survey may be requested. One thousand feet shall be the minimum distance for which a preblast survey may be requested, regardless of the above calculation. Residents outside of these boundaries may petition the Town Board for a preblast survey, with the survey to be at the quarry operator's expense. Residents denied this preblast survey may, at their own expense, secure a survey by a company acceptable to the quarry operator. The quarry operator may not unreasonably reject the company proposed to perform the survey. The surveys performed in this paragraph will serve as the basis for damage claims against the quarry operator. The blasting logs used to determine the previous three years' high, as referenced in this subsection, are available for inspection from the Town Clerk. [See § 182-3B(5).]
At the time of the permit application, the applicant shall have notified, in writing, all residents or owners of dwellings or other structures located within the affected area, previously defined in Subsection G(3)(a) immediately above, who may request a preblast survey. All preblast surveys shall include a water quality test for existing wells. The applicant shall cause a preblast survey to be conducted as to such dwellings or structures and extensive water quality testing for existing wells; provided, however, that the applicant shall not be required to conduct a preblast survey more than once every six years and a well water quality test more than once every four years. The applicant or permittee is responsible for the costs of all requested preblast surveys and water quality tests.
The survey shall include a written report signed by the person who conducted the survey. Copies of the survey report shall be promptly provided to the Town Clerk, the owner or resident, and the applicant/permittee. The owner, resident or applicant/permittee shall promptly submit in writing to the Town any objections to the survey report, setting forth in detail such objections.
The owner of a dwelling or structure that is within the affected area defined in Subsection G(3)(a) above, who subsequent to the preblast survey has substantially modified or improved the dwelling or structure by 50% or more of the fair market value, may request a new preblast survey. If it is found that a preblast survey is appropriate, the permittee may conduct such surveys within a reasonable period of time, but not exceeding twice a year for all such requests by all owners. These updated surveys shall be requested in writing submitted to the Town Board, which shall promptly notify the permittee of the request.
All expenses incurred as a result of such independent surveys shall be the responsibility of the applicant/permittee. Upon receiving and approving billings for such expenses, the Town shall cause notice of the expenses to be mailed to the applicant/permittee, who shall reimburse the Town for such expenses within 30 days after receipt of such notice.
Effective date. All use of explosives and blasting activity conducted in the Town shall be subject to the provisions of this chapter. Existing operations of whatever nature, including without limitation nonmetallic mining operations, shall comply with the terms of this chapter.
Other ordinances. Where the provisions of this chapter conflict with any provisions of any other Town ordinance, the provisions of this chapter, if more restrictive than those of the other ordinances, shall control and shall supersede the provisions of the other ordinances.
State and federal laws. Where the provisions of this chapter conflict with the provisions of any applicable state or federal law or regulation, the provisions of the most restrictive ordinance, statute or regulation shall control, to the extent permitted by state and federal law.
