Reporting Data to Ohio EPA

The reporting requirements for the small sanitary general permit have changed slightly with new permit OHS000002. Each table of limits and monitoring requirements has a specific outfall number associated with it to be used in reporting to Ohio EPA; also, the smallest discharges now must submit data to Ohio EPA once per year.

Limits and monitoring requirements are based on the average design flow of the treatment plant, rather than the actual flow. Permittees are covered under only one set of requirements, even if discharge flow varies. You should always report data using the outfall number for that set of requirements.

For example, if the treatment plant was designed to treat 2000 gallons per day, and the discharge is not directly to the Ohio River, you would be covered by the limits in Table III. A. 3. of the permit, and would report data as outfall 003. This is true even if the actual flow for the reporting period was less than 1500 gallons per day. These requirements are based on the average design flow. More information about Ohio EPA reporting forms can be found in our Form 4500/4519 How-to Booklet.

The previous version of this permit did not require reporting for permittees with design flows less than 1500 gallons per day. Records were simply required to be kept on-site. The new permit requires that data be reported to Ohio EPA annually.

Permittees covered by this permit may also report electronically using Ohio EPA's SWIMWARE software.
