Electronic Data Delivery for Tier I/II and Copper Biotic Ligand Model Monitoring

What permit holders need to know

The Oregon Department of Environmental Quality requires permit holders in Oregon to monitor for various toxic pollutants as outlined in Schedule B of the NPDES permit and uses the results to determine if the permit holder’s discharge is likely to cause or contribute to violations of Oregon’s water quality criteria through Reasonable Potential Analysis.
In order to streamline the receipt and analysis of this data, DEQ has developed an Electronic Data Delivery system.  Under EDD, permit holders provide DEQ with Tier I/II and Copper BLM monitoring data according to a standard format. The DEQ lab then reviews the data before providing it to DEQ permit staff. Please note that this process has recently (2019) undergone significant revisions to allow for submission of data to NetDMR and to better align with a standard data submission format which is compatible with our current data systems. Please read the instructions and FAQ page to ensure proper data submittal. 

 This information guide will help you:

  • Find out if you need to submit toxics data to DEQ
  • Submit Tier I/II and Copper BLM monitoring data to DEQ. The data must be submitted as a spreadsheet attachment through NetDMR, and include the following:
    • EDD (Electronic Data Deliverable) - an Excel spreadsheet that includes monitoring results according to a specific format. 
    • Tier II (or Level II) Analytical Lab Report
    • Chain of Custody information
