The Pennsylvania Department of Environmental Protection (DEP) announced on March 31, 2020, the U.S. Environmental Protection Agency advised the DEP that it had created a new No Data Indicator (NODI) code, NODI code “Z,” COVID-19, that permittees could use in conjunction with NPDES reporting requirements where the data is missing because of the COVID-19 pandemic, in order to avoid automatic generation of discharge monitoring report (DMR) violations for non-receipt of data.

In response, DEP advised that it would add NODI code “Z” to its eDMR System, but cautioned that permittees may only use NODI Code Z if the permittee has received written approval of their application to temporarily suspend regulatory requirements and/or permit conditions.

The DEP’s application for temporary suspension of a regulatory requirement and or permit condition is available here. The completed application should be submitted via email to More information on the DEP’s eDMR System is available here.
