    Rapid City does not require a general business license. The city's own licensing page states that the Finance Office requires a business license only for these types: Adult Oriented Business, Central Station Service, Ice Cream Vendor, Pawn / Precious Metals and Gems / Second Hand, Refuse Hauling, Security, Sidewalk Vending, Taxi, Transportation Network, or Alcohol Related Business/Event (Finance Office, 605-394-4143). It adds explicitly that if you do not have one of these businesses, the Finance Office does not require you to have a business license through their office, and refers other business licensing questions to the Department of Revenue at 605-394-2332. Contractor licenses, building permits, plan review, inspections, and air quality permits are handled separately by Building Services at 605-394-4120. A South Dakota sales tax license from the Department of Revenue is required and is free.

  2. Pressure Washing Wastewater Rules - No Rapid City or Pennington County Stormwater Permit

    Neither Rapid City nor Pennington County issues a stormwater discharge permit, wastewater disposal plan approval, or environmental registration for pressure washing businesses; there is no such permit product and no fee. Pennington County's Storm Water page describes the county's own MS4 permit and Storm Water Management Program, jointly managed by the Planning and Highway Departments and covering unincorporated areas - it is the county's permit for its system, not a permit businesses apply for. Rapid City runs a comparable municipal program inside city limits. What binds a pressure washing operator is the underlying prohibition: SDCL 34A-2-21 provides that no person may cause pollution of any waters of the state or place wastes where they are likely to cause pollution, and violations may be abated as a public nuisance. Practically, contain and recover wash water carrying detergents, degreasers, paint chips, or oils and dispose of it to a sanitary sewer connection with the utility's permission or to a licensed disposal facility rather than to a storm drain or gutter. The DANR Office of Water is the state surface water authority.
