When working on installations, repairs, replacements or upgrades of an underground storage tank system, the Documentation Requirements for UST Systems and Components guide can be used to determine what forms must be submitted to the DNR. Installers can use the UST Installation Paperwork Checklist (542-0075) to assist with paperwork. Some documents are due to the DNR 30 days in advance of work being started. ALLOW 10 BUSINESS DAYS for processing once all installation paperwork is submitted to the Iowa DNR UST Section.
