Read more about the new electronic reporting rule here:

The Electronic Discharge Monitoring Report (eDMR) process is an application for electronic submittal of Discharge Monitoring Report (DMR) data. The basic process involves logging in to the application, entering the DMR information, and submitting the information to the DEQ. Some of the benefits of using the eDMR application as opposed to paper DMRs include faster entry, information verification, viewing complete permit effluent history, and complete company held permit effluent history, and data that is more accurate. 

eDMR 3.0

The current version of eDMR is eDMR 3.0. Several updates and changes, have been addressed, including the issue with internet browser compatibility. eDMR 2.0 and 2.2 were only compatible with Internet Explorer 8, whereas eDMR 3.0 is compatible with Internet Explorer 10, Mozilla Firefox, and Google Chrome and Microsotf Edge. If you use Internet Explorer 11 please use the Compatibility View to be able to enter your data correctly.  Other changes and updates include a revamped main page, the addition of a navigation menu, and added functionality.

The web address for eDMR 3.0 is:

Before accessing eDMR 3.0, the permittee will have to obtain login privileges for their company and/or consultants to access the application. Accessing eDMR requires an eGOV ( and ENVITE ( account. A walkthrough guide for eGOV and ENVITE can be found at

Transition to NetDMR for Electronic WYPDES Discharge Monitoring Report Submittals 

This spring, the Wyoming Department of Environmental Quality (DEQ), Water Quality Division will begin transitioning to NetDMR for electronic submission of WYPDES discharge monitoring reports (DMRs). NetDMR is a web-based tool provided by EPA that allows permittees to electronically sign and submit DMRs to meet permit requirements. Previously, the Water Quality Division has facilitated electronic DMR submission through its eDMR system. As a newer system, NetDMR will offer streamlined sign-up and reporting processes to simplify DMR submittals for permittees and enhance benefits that include, but are not limited to, improved data availability, improved communication through email notifications, and improved data quality assurance/quality control. This transition is part of the Water Quality Division’s ongoing efforts improve efficiency and public transparency through the use of digital processes. In addition, the transition is an important component of ensuring compliance with the National Pollutant Discharge Elimination Electronic Reporting Rule.

In April, WYPDES staff will start contacting select permittees to begin the transition. Note that permittees will be transitioned to NetDMR in phases, and most permittees will not be contacted until the summer or fall to begin the transition. The DEQ anticipates a complete transition by the end of 2021. Outreach and training on NetDMR will be provided.

If you have any questions about NetDMR or this transition, please contact Kevin Campbell (, 307-777-2431) or Katherine McCrea (, 307-777-5990). If you are a permittee and would like to volunteer for an early transition to NetDMR, please contact either Kevin or Katherine.

For basic help assistance, the most important thing is to be as specific as possible. It is important that you supply all of the information to the Department of Environmental Quality (DEQ) so we can assist you the best we can. The following information is required: Permit Number, Outfall, Time Frame, Specific Problem, and any background information you feel is necessary. If you are using XML files, please attach a copy of the XML file to the email when notifying the DEQ.

eDMR 3.0 requires an active ENVITE account to access the application, which can be obtained by going both to and Instructions on how to set up an eGOV and ENVITE account can be found at

The DEQ asks companies to update the account information when personal or company information changes. To update the account information, please log in to ENVITE and go to “User Profile” to update any information.

eDMR accounts no longer need to be deactivated. Inactive accounts expire after 14 months from the last time the account was used. If the account expires and you want to use the inactive account again, you will have to request access to eDMR again.

eDMR 3.0 supports the following browser: Mozilla Firefox, Google Chrome, and Internet Explorer Versions 8-11. Other browsers, such as Opera or Safari, have not been tested but might work with eDMR 3.0.

The walkthrough document for the eDMR system can be found at the following link: 

The DEQ will also provide training at regular intervals.  Please contact Kevin Campbell at or 307-777-2431 for training inquiries.

First, it is important to know what an excursion is. An excursion is an exceedance of the permit limit and is defined by the number of samples taken during any given sampling period that are over the permit limit. Second, it is important to understand that the DEQ cannot and will not tell your company how to address an excursion. It is up to your company to put forth a good faith effort to prevent the problem, correct the problem, and prevent any further occurrence of the problem. The DEQ will take any enforcement action it feels necessary to address any exceedance issue.

If your company does have an exceedance make sure you fill out the “#Exceeds” field on the “eDMR Parameters” page with the appropriate information. The DEQ suggests that you address the issue in the “AddComment” column in the “Value Records” table in the same row as the exceeded limit value. Upon saving the information in the “AddComment” column, it will be permanently stored in the “Comment” column. At a minimum, it is suggested your company reports the date of the excursion, the supposed cause, and also the plan of action to address the issue. You will have the option of following up on the issue by adding more notes in the “AddComment” column upon receiving further information – i.e. further test results, outfall modification/renovations, process changes, etc.

Upon submittal of the information to the DEQ, the information will be reviewed and any action the DEQ feels necessary will be taken. Please understand that by self submitting this information to the DEQ it by no means removes any responsibility of the permittee to follow all regulations provided by the applicable WYPDES permit and Wyoming Water Rules and Regulations.

In order to enter Non-Detectable results, you can either use the manual method of changing the “NoDischType” in the “Value Record” or use the “Propagate” method. Please refer to the eDMR walkthrough for more information regarding these methods. The walkthrough can be found at

You will notice any foreign characters will not be allowed to be entered in the Value column. Characters such as <>+- will be removed and the value will be changed to zero. If you have an effluent result of <X (less than some value), please record the value as “Below Detection”. If you have a sample that is + or – X (plus or minus some value), please record the value only and leave off the precision. Please DO NOT enter “Zero (0)” when reporting a Non-Detectable result. Instead, please use “Below Detection Limit/No Detection” from the “NoDischType” in the “Value Record” table.

If you ever miss a sample you should try to collect one as soon as possible. There is a “NoDischType” code for Missed Samples (“Analysis not Conducted – No Sample”). It is recommended that you use the “Analysis not Conducted – No Sample” code for a missed sample, and then use the “AddComment” function to explain why the sample was missed and the plan of action to make sure there are no future missed samples. For help entering “No Discharge” Codes, please refer to the eDMR walkthrough at the following link:

If you think you are missing reporting information after reading the latest copy of your permit, there are two things that may be wrong. The first thing that you should do is check and make sure you are looking in the correct time frame. You need to make sure you are in the correct Effective Expiration range, and also the correct Interim Range. If you have exhausted all potential outfall/date combinations, there is a chance the information was not setup correctly in the system by the DEQ. If this is the case, it is vital that you contact the DEQ and notify them of the specific problem so that the information can be updated correctly. The DEQ will input the correct information into the database and will notify you when it is corrected.

If the information is in the eDMR application, but you think there is a problem with it, the best plan of action is to contact the DEQ. This problem may have occurred because the data was entered or set up incorrectly or because the data was incorrectly migrated from the old system to the new one. If you feel that there are any errors, please contact the DEQ with the specifics.

The main reason you will not be able to submit information to the DEQ is that the information you are trying to submit is not valid. Before submittal, make sure the “Overall Status” is valid (VAL) or the system will not allow you to submit the information. You can check the “Overall Status” by either going to the “eDMR Parameters” page (the page where sample results are entered) and clicking on the Validate button, in which case the system will tell you of any potential problems with the submittal, or by using the “Overall Status Utility” function. Please refer to the eDMR 3.0 walkthrough on how to use the “Overall Status Utility” function.

Before logging in to the application, your company will be required to set up an ENVITE account to access eDMR. Please refer to #2 concerning obtaining access to ENVITE and eDMR. If your company already has access to ENVITE and/or eDMR, the account setup might not be completed or might be locked due to invalid attempts. Please contact Kevin Campbell at or 307-777-2431 to reset the account.
