JULY 2024
The Maine DEP has prepared the draft 2024 Integrated Water Quality Monitoring and Assessment Report for submission to the U.S. EPA in accordance with state and federal reporting requirements,
This report is available for public comment until 5:00 PM on July 22, 2024. For more information and access to the documentation (2 files), please visit www.maine.gov/dep/water/monitoring/305b/. Reviewers of the Report document should pay particular attention to the Consolidated Assessment and Listing Methodology (CALM) required by the EPA for surface water assessments in this report. The CALM is described in Chapter 4 of the document.
For the first time, assessments for waters that present barriers to fish passage are included in a new Category 4-C-FPB (Fish Passage Barrier); the relevant CALM is included under the header ‘Support of Indigenous Species’. Specific surface waterbody attainment and impairment assignments can be found in the Appendices (a separate file). The appendices are broken into five waterbody types: rivers/streams, lakes/ponds, wetlands, estuarine and marine waters, and coastal designated beaches. Categories 1-3 are for waters that are not impaired, categories 4 and 5 are for waters or water segments that are impaired for one or more uses.
We encourage you to review the document and provide comments on the report. Comments become part of the public record and are published in the final version of the Report. All comments should be sent to:
By email: [email protected] By fax: 207-287-7826

MEWEA Peer to Peer Training
Ever wonder what it is like to be at a plant that is bigger/smaller, different technology than where you work? How other organizations handle issues that crop up at your facility? Now you have the opportunity to visit another facility, plus earn continuing education hours in the process through MEWEA’s Peer to Peer (P2P) training program.
P2P features customized, in-person training. The goal of the P2P training program is to encourage wastewater operators, mechanics, lab techs, and managers to visit wastewater facilities for a day to learn from the skills and experiences of others. The program is sponsored by MEWEA’s Treatment Plant Operators Committee. Areas of focus include:
- Operations
- Laboratory
- Collections
- Management
- Other (GIS, SCADA, IPP, etc.)
Note that credits will not be issued for just touring a facility. There must be a focused topic for training to be approved. While not a requirement for the host facility or person conducting the training, the person receiving the training must be a MEWEA member to participate and receive credits. All MEWEA members are eligible for up to 3 credit hours per year, and 6 credit hours per license cycle.
For additional information, contact the TPO Committee: [email protected] or visit: Operator Training (mewea.org).
Monthly Training Calendar and Training/Certification Resources.
The monthly training calendar, which lists training by not-for-profit organizations, is emailed to certified operators each month. It can be found at the DEP’s certification website https://www.maine.gov/dep/water/wwoperator/ under the Additional Materials section.
The NEIWPCC/JETCC website, https://jetcc.org/index.php provides information on signing up for an exam, training classes, and certification renewal. Contact Spring Conolly at [email protected] or call 207-253-8020 for more information.
Rental Assistance under the GI Bill®
If you are hiring a recent veteran for a water/wastewater position, they may be eligible for rental subsidies as they begin their new employment, according to Daryl Reed, SAA Assistant of the Maine Bureau of Veterans Services. They may also qualify for Apprenticeship and On the Job Training (OJT) programs. For more information, contact Daryl at [email protected] or leave a message in the Maine SAA inbox at [email protected].
Water Warriors Jobs Initiatives
Many skills learned in the Armed Forces, particularly with equipment maintenance and science based programs, translate well into a successful career protecting the one thing no one in our country can live without, clean water. At the same time, many of our most qualified water/wastewater operators are reaching retirement age, leaving the industry with a labor shortage, not to mention the imminent loss of decades of institutional knowledge.
The Water Warriors Jobs Initiatives (WWJI) is a joint effort by the New Hampshire Water Pollution Control Association (NHWPCA) and the Maine Water Environment Association (MEWEA) to recruit and retain returning and retiring U.S Armed Forces veterans into the drinking water and clean water infrastructure fields. The WWJI promotes the water/wastewater field as a desirable career option for returning veterans. The objectives include:
- Providing education and training opportunities,
- Streamlining the certification process for our veterans, and
- Providing placement assistance and internships.
This initiative will require the coordinated efforts of industry leaders, veterans’ organizations, and government agencies, but the end result, getting veterans into good paying jobs while serving their communities, is worth it.
Please take a look at this video about military veterans entering the drinking water/ clean water fields: https://vimeo.com/user57485243/review/848142594/bd1bd8e4e9.
The timing has never been more opportune to provide those who served our country with a career that will provide for their future, while still allowing them to serve their local communities. The MEWEA contact is Peter Goodwin, [email protected], if you would want to learn more about providing a returning veteran an internship at your facility or would like to participate in this exciting initiative.

a. Polymer
b. Chlorine
c. Lime or sodium bicarbonate
d. Methanol
11. The following information is given for a plant performing nitrification:
Plant influent flow = 10 mgd
Plant influent BOD = 180 mg/L
Plant influent TKN = 35 mg/L
BOD removed in Primary clarifier = 30%
TKN removed in Primary clarifier = 10%
Pounds of oxygen required for each pound of BOD removed = 1.1
Pounds of oxygen required for each pound of ammonia nitrified = 4.57
a. How many pounds of oxygen per day are required for BOD removal?

2. c. Raw wastewater influent contains ammonia and organic nitrogen
3. a. TKN stands for Total Kjeldahl Nitrogen
4. c. You would expect to see the highest TKN levels in the influent
5. c. Typical ammonia levels in the influent are in the range 25 to 30 mg/L
6. a. Nitrogen compounds in wastewater final effluent can be toxic and/or cause eutrophication (excessive algae growth) in the receiving stream
7. c. Cannot test nitrogen compounds for permit compliance unless your lab is state-certified
8. a. Nitrification is the process in which nitrifying bacteria convert ammonia to nitrite, followed by nitrate
9. d. Good conditions for nitrification in a wastewater plant include high oxygen levels, warm temperature, and Mean Cell Residence Time (≥5 days)
10. c. If you need to add alkalinity to a nitrification process to keep the pH from dropping, possible chemicals you can use include lime or sodium bicarbonate
11. Using the pounds formula:
a. 10 mgd X 180 mg/L X 0.7 (remaining after PC) X 1.1 lb oxygen
= 11,559 lb/day oxygen required for BOD removal
b. 10 mgd X 35 mg/L X 0.9 (remaining after PC) X 4.57 lb oxygen
= 12,006 lb/day of oxygen required for conversion of ammonia to nitrate
12. a. Nitrification causes the oxygen requirement to double.
