General Permit #5 (GP #5) authorizes discharges from facilities primarily engaged in mining or quarrying to waters throughout the State of Iowa. GP #5 was reissued on July 20, 2021. The types of discharges authorized under GP #5 include:
The facilities covered by General Permit #5 may be primarily engaged in mining or quarrying the following:
The reissued version of GP #5 became effective on July 20, 2021.
Changes to this version of the permit included formatting, additional definitions, minor revisions to simplify and clarify the permit language, and the inclusion of applicable state rules. The permit definition for “Waters of the United States” was updated to reference the June 22, 2020, federal definition. This is the effective date of the final Navigable Waters Protection Rule published by the U.S. EPA.
On August 16, 2022, the Environmental Protection Commission adopted a final rule to renew GP #5 with minimal changes. The renewed permit will become effective on July 1, 2023. Note that under the adopted rule, any discharge authorizations granted under the current version of GP #5 issued on July 20, 2021, will remain valid through the renewed permits' expiration date of June 30, 2028.
For more information on the renewal, please see the NPDES Rules page.
Notices of Intent, Annual Monitoring reports, and Fees for General Permit #5 may all be submitted electronically using the General Permits 5, 8, and 9 Database. For more information on the database, and to access the user manual, please see the NPDES Databases page.
A permitted facility has the option of submitting an annual fee, or a three, four, or five-year fee as follows:
Fees are to be submitted by August 30 each year unless a multiple year fee payment was paid in an earlier year. New facilities will still have to pay an annual fee by August 30th even though they may have months remaining on their original fee payment. For example, if a new facility paid a one year fee with their NOI on April 1, 2021, the facility would still have a new annual fee due on August 30, 2021.
In the event a facility is no longer eligible to be covered under general permit #5, the remainder of the fees previously paid by the facility would be applied toward its individual permit fee.
Fees for General Permit #5 may all be submitted electronically using the General Permits 5, 8, and 9 Database.
