A Louisville car wash seller should resolve the MSD wastewater-permit handoff, document drainage obligations and reconcile any flood or closure history with earnings. Where a discharge permit applies, it is issued to the particular user and operation; the buyer should not assume it transfers with the equipment or deed.

Treat the discharge permit as a specific closing dependency
MSD’s currently linked June 2022 regulations state in §4.02.7 that wastewater discharge permits cannot simply be reassigned, transferred or sold to a new owner, user, premises or changed operation. The section calls for the seller to notify the successor by letter of the new-permit requirement, send a copy to MSD, and for the successor to submit an application within 30 days of the ownership transfer. Required self-monitoring must continue without interruption.
Apply that process to the facility’s actual permit with MSD. Identify the permit holder, expiration, discharge locations, reporting calendar and pending notices. Ask who will sign and submit the successor application and which sampling or service contracts must continue through closing.
Do not turn the 30-day application provision into a promise that approval takes 30 days or that every proposed operational change is allowed in the meantime. Retain the agency’s direction on the specific transaction. A buyer’s new equipment plan can create a different review question from an unchanged operation.

Compare the approved process with the current wash
MSD’s commercial and industrial process review addresses pretreatment equipment, separation of process lines and suitable monitoring locations during planning and construction. For an existing wash, obtain the approved plans and compare them with the current plumbing, interceptor, equipment and chemical-storage layout.
Collect maintenance and waste-removal records, sampling reports and any corrective-action correspondence. If a contractor changed the process or a buyer proposes additional equipment, document what changed and ask whether an updated review is needed. A building permit and a wastewater approval answer different questions.
For a leased wash, clarify which equipment, underground lines and drainage assets belong to the business and which to the landlord. The buyer needs a practical path for maintenance access as well as a list of assets included in the sale.

Do not treat a small site project as automatically exempt
MSD reviews land disturbance in Jefferson County and sewer extensions within its service area. Its guidance distinguishes small commercial work, site disturbance and other project categories. It includes commercial work below 2,000 square feet of disturbance in a small-project permit category; that threshold is not a blanket exemption from review.
If a buyer plans additional paving, vacuum spaces or a building addition, ask the designer to identify the relevant drainage, erosion-control, water-quality, sewer and floodplain reviews. Keep a proposed layout separate from an issued approval. The sale of an operating wash should not be marketed as approval of an unreviewed expansion.
Locate maintenance agreements, easements, detention features and inspection records. Record who maintains each drainage asset and whether the work is included in historical operating expense. An obligation assigned to the property can matter even if the seller has not spent money on it recently.

Separate river, stream and local drainage exposure
MSD identifies Ohio River flooding, flash flooding from interior streams and overloaded storm systems as different local concerns. Request parcel-specific flood and drainage records rather than assuming that distance from the river settles the question. Pair mapped information with actual claims, repairs and interruption dates.

| Record to collect | What to reconcile | Sale decision it supports |
|---|---|---|
| Discharge permit and reporting calendar | Holder, conditions and uninterrupted monitoring | Successor application and operating responsibilities |
| Process plans and maintenance records | Approved plumbing versus installed equipment | Corrections and future equipment review |
| Drainage plans, easements and agreements | Assets, access and maintenance duties | Ongoing expense and expansion constraints |
| Flood history, claims and daily closure log | Type of event and actual operating effects | Insurance diligence and earnings explanation |
Obtain property-specific insurance terms and keep any proposed protection measures as proposals until supported by design, cost and approval. Community flood-protection programs do not establish the premium or risk for the wash.

Keep event costs and continuing obligations distinct
Illustrative example: a seller incurred $16,000 for cleanup after a documented water event and received $10,000 of insurance proceeds. Reconcile how both amounts entered the accounts and identify any deductible, unpaid claim or continuing repair. Do not add back the full cleanup bill while ignoring the recovery already recorded.
If a detention facility also needs routine maintenance, evaluate that recurring obligation separately. A one-time invoice does not prove that all future drainage costs disappear. Likewise, estimated revenue lost during a closure should not automatically be added to normalized earnings.
The first sale discussion should leave the owner with a named person for the MSD handoff, a current monitoring calendar and a clear list of unresolved site work. That is a stronger foundation for negotiations than assuming the permit and property obligations move automatically.
Owner questions
Does a Louisville MSD wastewater permit transfer with the sale?
The currently linked regulations say it is specific to the user and operation and is not simply transferable. §4.02.7 describes seller notice, a successor application within 30 days of transfer, and uninterrupted required monitoring. Confirm the site-specific steps with MSD before closing.
Is a project disturbing less than 2,000 square feet exempt from MSD review?
Not automatically. MSD’s guidance includes small commercial disturbance below that size in a permit category. Have the project scope classified by MSD and the responsible designer.
Is a wash away from the Ohio River free of flood concerns?
Distance from the river does not resolve stream flooding or overloaded storm-system issues. Use parcel records, drainage plans, claims and actual interruptions to evaluate the property.
