JETCC is pleased to announce that the 10th year of Management Candidate School will begin on November 14th in Bangor. Thank you to Bangor Water District for hosting the Class of 2019!
The Management Candidate School (MCS) is an 11-month training program that provides the intensive training, networking and skill-development coursework necessary to prepare the next generation of water and wastewater managers and leaders. With many of Maine's current water and wastewater managers at or near retirement age, it is hoped that the individuals who complete the MCS program will be able to continue the critical work of managing the state's water and wastewater treatment infrastructure. This exciting training program is aimed at mid-level operators with management potential.
This year’s MCS class of 23 wastewater and water operators will be graduating at the MEWEA Convention in September, bringing the total number of MCS graduates to 175. Visit JETCC’s website at www.jetcc.org for updates.
Maine Rural Water Association's 38th Annual Technical Conference & Tradeshow, December 4 through December 6, 2018 at the Cross Insurance Center in Bangor is now open for registration.
The
conference provides a great opportunity to connect and learn from others in the
field through education, leadership, recognition and community.
For more information or to register, go to www.mainerwa.org or call 207-727-4092.
Also just around the corner is NEWEA’s 2019 Annual Conference & Exhibit, January 27-30 at the Boston Marriott Copley Place in Boston. The conference, Water’s Worth It, Let’s Go All In consistently attracts over 2,100 engineers, consultants, scientists, operators, students and features a variety of technical sessions and over 200 exhibitor displays.
The conference provides an opportunity for professional exchange of information and state-of-the-art concepts in wastewater treatment and other water environment issues.

Question 2: Bond Issue (Public Law 425)
Do you favor a $30,000,000 bond issue to improve water quality, support the planning and construction of wastewater treatment facilities and assist homeowners whose homes are served by substandard or malfunctioning wastewater treatment systems?
If approved, this bond will fund three wastewater infrastructure /water quality grant programs at DEP that provide grants to upgrade municipal/ quasi-municipal wastewater infrastructure (treatment plants, pump stations, sewer systems), remove overboard discharges and repair/replace malfunctioning septic systems that impact surface water.
$27,650,000 of these funds will be for municipal/ quasi-municipal wastewater infrastructure.
• All three programs create jobs, improve water quality, and protect and/or open shellfish areas.
• These bond funds will be combined with other federal and state funds to facilitate important wastewater infrastructure projects. An estimate of the leveraging potential is 150% or more, resulting in approximately $71,475,000 of wastewater infrastructure projects.
• A broad coalition of stakeholders support this bond due to the multiple benefits of job creation, environmental protection, improvement of shellfish harvesting areas, and municipal/ quasi-municipal infrastructure improvement.
• It is estimated that 540 jobs (such as construction and engineering related jobs) will be created or sustained from the bond funds and 1,287 total jobs will be created or sustained from the combined bond and leveraged state and federal funds. [1]
• Shellfish harvesting jobs: In addition to the jobs noted above, abating combined sewer overflows, removing overboard discharges, and repairing/replacing malfunctioning septic systems all have the potential to open closed shellfish areas so they can be harvested.
There are approximately $1 billion of known needs to upgrade Maine’s municipal wastewater infrastructure. Based on current known needs there are numerous projects that are good potential candidates for grant funding.
DEP will solicit detailed project requests to determine how the grants will be awarded. Project requests will be evaluated using longstanding DEP criteria including economic need, shellfish area protection and improvement, abatement of combined sewer overflows, water quality improvement, regionalization, and leveraging bond funds with other state and federal funding sources.

DMR-QA Corrective Action (CA) reports and retests are due October 26, 2018 for those facilities who received a “not-accept” on the first test. The CA can be a short email describing why you think you failed and what changes you made to correct the problem for future testing.
If you failed a parameter and would like laboratory technical assistance from the DEP, let myself or your inspector know.

NetDMR Data Sync with EPA’s Computer System
Ever wonder what happens to the NetDMR data once submitted? Or why, if the system is having problems, your inspector may ask you to wait a day and try logging in after the system has time to update?
Once DMR data is submitted by the facilities through NetDMR, it goes to an EPA computer system called the Integrated Compliance Information System, known by its abbreviation, ICIS.
ICIS is an integrated data system utilized by EPA and State authorities to support management requirements of Compliance and Enforcement programs. NetDMR is one of the systems from which ICIS collects and transmits information.
ICIS and NetDMR “communicate” with each other in two important ways:
1) DMR data that is submitted through NetDMR is uploaded to ICIS to determine compliance with permit and schedule requirements.
2) NetDMR gets its DMR parameter and schedule information from ICIS.
A recent update to ICIS addresses item 2) above. The DMRs available in NetDMR, as well as the parameters listed on the DMRs, are generated based on information stored in ICIS. When changes are made to a schedule or parameter requirement in ICIS these changes are not automatically or immediately updated in NetDMR. It is important for NetDMR to have the most recently updated information from ICIS prior to users entering and submitting DMR data so users do not receive violations due to unsubmitted DMR data.
Prior to the high level webservice implementation, the two systems relied on a manual process performed by the regulatory authority to remain in sync. This process also took up to one day for changes to be reflected in NetDMR.
The high level webservice adds five additional (mostly automated) means for the two systems to be synched with one another. The two systems will automatically be synced when any one of the following tasks are performed within NetDMR:
1) Edit/Correct DMRs
2) Create Unscheduled DMR
3) Import DMRs
4) Sign and Submit DMRs
Users can also manually update information in NetDMR using the search function, this works when searching for DMRs and CORs. Under most circumstances this should not be necessary due to the four previously mentioned tasks which should ensure the two systems remain in sync.
The addition of webservices updates will help ensure that NetDMR and ICIS are up to date with one another whenever a user is entering DMR data. This should reduce errors caused by entering results into DMR forms that are out of date with the most current information stored in ICIS.
If you would like more information about synching information in NetDMR using the search function, or have any other question regarding NetDMR, please contact Brett Goodrich at 207-287-9034 or Brett.A.Goodrich@maine.gov.
1. a) 2.4 fps
Use the formula: Flow = Velocity X Area
Solving for Velocity = Flow/Area
Area = 3’ X 1.5’ = 4.5 sf (note: this is the cross-sectional area)
Change flow from MGD to cfs:
Flow = 7,000,000 gal/day/1440 min/day/60 sec/min/7.48 gal/cf = 10.83 cfs
Velocity = 10.83 cfs / 4.5 sf = 2.4 fps
2. a) 440 gpm
Using the same formula as above: Flow = Velocity X Area
Find the cross-sectional area: 0.785 X 0.5’ X 0.5’ = 0.2 sf
Velocity is given as 5 fps
Flow = 5 fps X 0.2 sf = 1 cfs
Convert to gpm:
1 cfs X 7.48 gal/cf X 60 sec/min = 440 gpm
3. b) 19,377 gal
Change 8’ 3” to feet = 8 + 3/12 = 8.25’
Volume = 0.785 X D X D X Depth X 7.48 gal/cf
= 0.785 X 20’ X 20’ X 8.25’ X 7.48 = 19,377 gal
4. a) 71.43 mL
Set up a proportion of the two concentrations:
(? mL x 0.28N) = (100 mL x 0.20N)
Solve for the amount of 0.28N reagent you need
? mL = (100 x 0.2)/0.28 = 71.43 mL
5. d) 14.6 lbs
Use the pounds (dosage) formula:
Pounds = Flow, MGD X concentration, mg/L X 8.34 pounds/gal
Pounds = 0.875 MGD X 2.0 mg/L X 8.34 = 14.6 pounds
