Answers from the rulebook for Town of Crosby

Rules another office applies inside Town of Crosby

Town of Crosby does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

  • Building code adoptedPartial

    Buildings inside Crosby town limits to which the Mississippi Fire Prevention Code applies, including public-assembly buildings and permitted buildings at least seventy-five feet high.

    • The cited state Fire Prevention Code applies to all state-owned buildings; public-assembly buildings unless a county or municipality has adopted a code at least as stringent; and permitted buildings at least seventy-five feet high unless the local code meets that standard.
    • The source does not establish whether Crosby adopted, opted out of, or enforces a local uniform building code.
    “The State Fire Marshal shall promulgate the Mississippi Fire Prevention Code which shall apply to: 1. All buildings owned by the State or State Agencies; 2. All buildings utilized for public assembly, except in any County or Municipality which has adopted a Fire Prevention Code with standards not less stringent than the Mississippi Fire Prevention Code; 3. All buildings, the permits for the construction of which are issued subsequent to the effective date of Sections 45-11-101 to 45-11-111 and which are not less than seventy-five (75) feet in height; provided, however, that in any county or municipality which has adopted a fire prevention code with standards not less stringent than the Mississippi Fire Prevention Code, the provisions and enforcement mechanism thereof shall apply and not the Mississippi Fire Prevention Code.”

    • MSDH lists both Amite and Wilkinson in its South Region.
    • This claim concerns individual on-site wastewater systems, not municipal sewer-service administration.
    “The On-site Wastewater program develops policy and regulations and provides technical assistance to regional environmentalists in designing and inspecting Individual On-site Wastewater Disposal Systems (IOWDS), recreational vehicle campgrounds/lodging parks, septage pumpers/haulers and individual water supplies.”

    • The application advises selecting inspection when home financing is involved and says MSDH will not approve a system after installation if a mortgage company, utility, local municipality, or other entity requires it.
    “Do you wish for the Department to inspect the installation of your on-site wastewater disposal system. NOTE: If home financing is involved, we advise you to select Yes. We will not approve the system after installation if the mortgage company, utilities, local municipalities, or other entities require it.”
  • Off-grid sanitationProhibited

    • Wastewater must instead be piped to central sewer or a septic system for proper disposal.
    “Mississippi does not recognize gray water. Anything that could be considered gray water in other states is classified as wastewater in Mississippi. All wastewater is required to pipe into a central sewer system or a septic system for proper disposal. No “gray water” can be discharged on the ground, ditches, or bodies of water.”

    sewer-line referral distance: <= 1 mile (MSDH requires a sewer-provider Letter of Rejection before it can proceed with the application)

    “State law requires you have permanent sewage disposal solution available to receive a permanent water meter. Permanent sewage disposal solutions can be a sewer line or septic system. [...] MSDH automatically refers applications within one (1) mile of a sewer line to connect. We must receive a Letter of Rejection from the sewer provider before we can proceed with the application.”

    “Staff engineers review and authorize Certified Professional Evaluator's designed On-site Wastewater Disposal Systems, Commercial Developments (Subdivisions, Manufactured, Multi-family, RV Campgrounds/Lodging Parks), Commercial Establishments (Restaurant, Child Care Facility/School. Church, Shopping Center, Office, etc.), review and approve manufactured designs of wastewater components, etc.”
