IAQ and IPM strategies for Microbial Pests

October is bringing predictably cooler temperatures, which means we’ll all be spending more time indoors. Indoor air quality (IAQ) is well known to affect human health and academic performance, but the pandemic has brought renewed attention. Now is a good time to take a second look at both ventilation systems and cleaning/disinfecting protocols to make sure all processes are working optimally and that staff have completed the necessary training.

Ventilation and Filtration

Our understanding of coronavirus has evolved in the past ten months, and we now know that people can become infected merely by sharing air, especially in close quarters. While wearing masks, installing barriers, reducing occupancy, and holding classrooms outdoors are good strategies, schools are also implementing additional ventilation and air filtration processes to reduce risk of disease transmission while also improving overall indoor air quality. Ventilation and filtration of indoor air may be at least as important, if not more so, than surface disinfection for reducing the risk of COVID-19 transmission1,2. And, with increased use of cleaning and disinfectant products, it is especially important to ensure that indoor spaces are adequately ventilated.

The simplest way to increase ventilation is to open screened windows and doors for cross-ventilation of indoor spaces, if doing so does not compromise safety or interfere with normal operation of ventilation systems. This is less ideal as temperatures drop, but may offer a temporary way to improve IAQ (and reduce risk of coronavirus transmission) in buses and some classrooms.

Portable air cleaners can also help. Environmental engineers at the University of Colorado Boulder and Harvard have created a guide on selection and use of portable air cleaners for schools.

Environmental engineers also recommend increasing settings on mechanical ventilation systems to six to nine fresh air exchanges per hour, if possible. When more people are in a space, the air exchange rate should be at the higher settings. The American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) provides detailed checklists and comprehensive guidance on ventilation and filtration to help schools slow transmission of viruses and improve indoor air quality via HVAC systems in ‘Reopening of Schools and Universities’. Consult with your HVAC specialist before making any changes to operation of your HVAC system.

Cleaning and Disinfection

Selecting the right cleaning and disinfecting products and using them correctly is critical to the health and safety of the people in your care—including your own staff. Some products may pose unnecessary health risks, may be ineffective against coronavirus, and/or are not permitted for use in Maine schools. Avoid learning after the purchase, that the sales rep was misinformed about Maine’s regulations or was making false claims.

Before purchasing any products, obtain and read both the product label and Safety Data Sheet (SDS) and verify that the products under consideration are permitted for use and will be appropriate for the intended purpose. For disinfectants and sanitizers, the product label has instructions on how and where to use the product, what PPE may be required, the required contact time, and more. You must read and follow the label! Disinfectant labels are legal documents that clearly state, “It is a violation of Federal law to use this product in a manner inconsistent with its labeling.” The SDS has additional chemical safety information but lacks the critical information found only on the product label. Obtain the product label from your distributor or contact the Maine Board of Pesticides Control.

Because many disinfecting and sanitizing products share similar trade names, refer to the product’s unique identifier—the EPA Registration Number (EPA Reg. No.) found on the label. Keep a copy of both the product’s label and the SDS in your school’s pest activity logbook, along with a written record of were, why, how and by whom, these sanitizing or disinfectant pesticides are used in your schools.

Using Electrostatic or Other Powered Sprayers? Governor Mills issued Executive Order 7 FY20/21, temporarily suspending some pesticide applicator licensing requirements, thus permitting the unlicensed use of powered sprayers for routine disinfection by qualified staff. To qualify for this temporary exemption personnel must complete School Disinfectant Applicator Training and the associated on-line exam to receive a certificate.

Non-school employees, including contracted cleaning services and bus drivers are not included in this license exemption and must have a full Commercial Pesticide Applicator’s license for powered disinfectant application. All other pesticide applications on school properties, powered or not, also require a Commercial Pesticide Applicators license. Contact the Maine Board of Pesticides Control for more information.

Efficiency Maine Helps Brighten More than 50 Maine Public Schools with Incentives to Support Lighting Upgrades

More than 50 Maine public schools are upgrading the quality of their interior and exterior lighting through a special Efficiency Maine initiative.

The principal goal of Efficiency Maine’s School Lighting Retrofit initiative is to reduce electric energy consumption from Maine K-12 municipal schools and to accelerate the conversion to efficient LED lighting. The offer supported project work for electricians and encouraged schools to complete the lighting conversions over the 2020 summer while school buildings are unoccupied.

“We were very glad to see broad participation stretching from Kittery to Calais to the County,” said Michael Stoddard, executive director of the Efficiency Maine Trust.

Eligible electrical efficiency lighting retrofit projects include interior and exterior lighting upgrades in classrooms, hallways, lobbies, entryways, stairways, auditoriums, libraries, cafeterias, offices, gymnasiums, parking lots, and public restrooms.

“This grant program will help 50 schools across the state to have better lighting while conserving energy and reducing costs,” said Dan Burgess, director of the Governor’s Energy Office. “This initiative not only helps our state meet its energy goals, but it allows schools to use the savings to support students and teachers in other important ways.”

Limestone Community School in Limestone is among the schools that has benefited from the incentive program. The school received more than $38,000 in incentives to upgrade lighting in its classrooms, auditorium, library, offices, bathrooms and parking lot. The school will see an estimated annual savings of more than $19,000 (129,975 kWh) and will realize a return on investment in an estimated 2.3 years.

 According to Superintendent Bill Dobbins, they are elated with the results and already have received inquiries from other district schools interested in pursuing similar projects.

“We viewed this project as a way to create a better atmosphere for the educational growth of our children,” explained Dobbins. “Efficiency Maine’s School Lighting Retrofit program enabled us to combine and accelerate two projects that our budget alone couldn’t accommodate in the same year. We were able to complete it using less money from Limestone taxpayers and while the children weren’t in school. We’re hoping the new brighter, uniform lighting will make it easier for them to do their schoolwork. In the meantime, we’ve already heard from our local police department that it’s easier for them to patrol the school grounds because the exterior lighting is so improved.”

St. John Valley Technology Center in Frenchville is equally satisfied. The school contributed approximately $20,000 to the project and Efficiency Maine contributed $13,000 to upgrade lighting in its entryways, hallways, and gyms. The school will see an estimated annual savings of nearly $7,000 (46,163 kWh) and will realize a return on investment in an estimated 2.8 years.

“There’s no question, improving lighting enhances the ability of students to learn,” said Kevin Lavoie, director of St. John Valley Technology Center. “We’re reducing our carbon footprint because LED lighting is more energy efficient. This program also has reduced the tax burden on our community and has created jobs for Maine’s workforce. That’s a triple win as far as we’re concerned. In addition, we’re especially pleased we could complete the project this summer.”

Songo Locks Elementary School and the Educational Services building for the Lake Region Vocational Center in Naples have brighter futures, as well. Together, the schools received more than $10,000 in incentives to upgrade exterior lighting and will see an estimated annual savings of more than $5,000 (39,481 kWh).

 Andrew Madura, director of Transportation, Facilities and Food Services for Naples schools, is confident the projects will help the schools save money and energy. Two years ago, Madura managed an interior lighting project using incentives from Efficiency Maine, which resulted in a 20% to 25% reduction in energy consumption for those measures.

“We’re constantly looking for ways to be more efficient,” explained Madura. “With a limited budget, this program was very helpful. We were able to complete both projects without allocating additional capital funds. It has particularly benefited the Educational Services building, which houses our buses and equipment. The exterior lighting at the building is on constantly in the evenings for security purposes, making the energy consumption fairly high.

“The nighttime staff have noticed and appreciate the improved lighting,” said Madura. “Aesthetically, it’s much more attractive. It’s also more controlled lighting, ensuring that our residential neighbors don’t experience light spill. Overall, we now have better lighting that requires less maintenance and uses less energy. To me, that’s an efficiency trifecta.”

Louis DiFrederico, facilities manager for the Millinocket School Department, managed projects at Stearns Junior – Senior High School and Granite Street Elementary School. DiFrederico already is a firm believer in the savings he can derive from Efficiency Maine initiatives, having managed a similar lighting upgrade 10 years ago with incentive funds. This time around, the projects improved lighting in the gymnasiums and corridors at the high school and upgraded lighting in the elementary school classrooms, hallways, cafeteria, and lobby. By matching Efficiency Maine’s incentives, DiFrederico estimates the school department will save $7000 a year for the elementary school and $6000 a year for the high school.

“Given the nature of limited school budgets and funding, I had to look for creative ways to get the job done,” explained DiFrederico. “This was a relatively easy process that was readily available and translated into real dollar savings up front and long-range. Without Efficiency Maine’s incentives, I would not have been able to complete these projects.”

DiFrederico was especially keen after he did the math. He calculated that by upgrading the lighting in all the elementary school classrooms energy load dropped from 1100 watts per classroom to 400 watts. Together, both projects will save an estimated 87,000 kWh annually.

“It used to cost $1.33 a day to light each elementary school classroom and now it costs 48 cents,” he said. “The new LED fixtures not only provide better light, but they look better, and provide a modern update to the buildings. Teachers and staff have also thanked me for brightening their classrooms and the building. To me, those benefits are a win-win for the district.”

Efficiency Maine accepted applications for the School Lighting Retrofit Funding Opportunity Notice (FON) between February 10, 2020, and June 1, 2020. The funding opportunity is now closed. Funding was calculated based on the amount of electricity saved by each project in the first year and was subject to caps of 80% of the total project cost and $100,000 per school district.

Efficiency Maine’s Prescriptive Program, which funded the school initiative, offers fixed incentives to reduce the cost of projects and to improve energy efficiency for businesses, municipalities, schools and higher education facilities, manufacturing and other industrial facilities, other non-residential facilities, and multifamily and condominium buildings with five or more units.

Extended Deadline: Funding Opportunity Notice for School Lighting Projects

To date, Efficiency Maine has received more than fifty applications for school lighting projects as part of this Funding Opportunity Notice. In fact, one project has already been completed.

Because of the level of interest, we have extended the deadline for a second time to allow more schools to apply — Efficiency Maine has extended the deadline for the School Lighting Funding Opportunity Notice to June 1, 2020. This decision has been made so that all parties involved will have more time to work through logistics and take part in these elevated incentives. Efficiency Maine does not oversee interactions between school personnel and the Qualified Partner; the program trusts that you will work with your contractor to determine how to handle site assessments and projects.

Efficiency Maine has extended the deadline for schools to apply through CIP FON-001-2020 for enhanced financial incentives to convert old, inefficient school lighting to LEDs.  Funding will be provided as an incentive of $0.30/kWh saved (first-year savings) capped at $100,000 per school district. Applications may be submitted through June 1, 2020.

PRIORITY NOTICE: Expanded Authority of Reserve Funds

An Act Regarding the Reserve Funds of Certain School Organizational Structures was signed by Governor Mills on March 12, 2020 and will become effective on June 16, 2020.

The contents of the new legislation are summarized below and may be of interest to leaders of some School Administrative Unit (SAU)s. Administrators may wish to consult with legal counsel regarding the procedures for establishing reserve funds for their school organizational structure.

School Administrative Units included in this act are School Administrative Districts (SADs), Regional School Units (RSUs), Community School Districts (CSDs), and Career and Technical Education (CTE) Regions.

Previously, School Administrative Units were able to establish a reserve fund for school construction projects and for financing the acquisition or reconstruction of a specific or type of capital improvement. This new legislation provides additional flexibility to create reserve funds for any of the following: regular education, special education, career and technical education, other instruction such as summer school and extracurricular activities, student and staff support, system administration, school administration, transportation and buses, facilities maintenance, debt service and other commitments; and all other expenditures including school lunch. The request for the reserve fund must be included in the district budget and have a description of the purpose for the reserve fund. The governing board is the trustee of the reserve fund, and in the cases of SADs, RSUs and CSDs, the fund must be deposited or invested by the treasurer as directed by the governing board.

Previously, Boards of Directors of any of these SAUs were able to expend money from reserve funds only if they were authorized to do so by a vote at a district budget meeting and an article for the purpose for the reserve fund had been in the warrant calling the meeting. However, this legislation now also provides the Boards of Directors with the ability to expend funds when the expenditure is required by law or in an emergency where the cost of a district vote is prohibitive. The governing board of the SAUs may expend the funds after providing public notice of a regular or special meeting, at which a vote to expend funds from the reserve fund will be taken. A public hearing must be held prior to the vote to expend funds from the reserve fund, and the vote must be recorded in the meeting minutes.

Step 1 – Reserve fund proposed in the budget for specific purpose is approved

Step 2 – Reserve fund set aside in SAD, RSU, CSD organizations

Step 3 – To expend the funds in the budget year, provide notice and:

  1. Hold a district meeting, OR
  2. Hold a regular or special meeting of the governing board with a public hearing, vote, and recorded vote.

For CTE regions, the cooperative board may expend the reserve fund if permitted by any indebtedness secured by the reserve fund and if approved in the region budget. A separate article for that purpose must be included in the budget proposal.

Please reference PL 2019 Chapter 588 for additional information.
