Energy Efficiency and VRWA

by Dmitri Hudak, Energy Efficiency Specialist

I am pleased to announce that as of November 1, 2010 I am serving the water/wastewater community in a new and exciting position here at VRWA. Under a new subcontract VRWA has with Efficiency Vermont, my primary focus is to assist with identifying energy efficiency opportunities within the water/wastewater treatment sector. The goal of this joint venture between VRWA and EVT is simple: to assist communities in becoming more energy efficient in order to reduce their long term operating costs.

As the ARRA circuit rider, I have had the great pleasure of making site visits and discussing financing options with operators and board members alike. This provided me with the opportunity to meet a lot of great people around the state. I will continue to travel the state maintaining the contacts that I have developed while shifting the focus from discussing financing options to identifying efficiency opportunities.

I welcome input and ideas from our membership base. If you have an idea for a project that will improve the energy efficiency of your operation, please let me know about it! I can be reached at 802-660-4988 x338 or email me.


Vermont's New Groundwater Withdrawal Rules

Eric Hanson, Source Protection Specialist

As all public water system operators in Vermont know, there are longstanding regulations in place concerning the permitting of sources and the operation of public water systems to help ensure adequate quantity and quality of drinking water for all water users connected to these systems. Because the majority of public water systems in Vermont obtain their water from groundwater sources, potential impacts to groundwater, such as interference with nearby water supply sources, are routinely evaluated during the permitting process for new public water system wells. Up until now there have not been similar requirements for commercial or industrial groundwater withdrawals in Vermont, such as those associated with golf course irrigation, industrial processes, and large bulk and bottled water operations. New rules - the Groundwater Withdrawal Reporting and Permitting Rules - are currently making their way through the administrative procedures process on their way to becoming officially adopted by the State of Vermont.

The Groundwater Withdrawal Reporting and Permitting Rules are a result of Act 199 of the 2007-2008 Vermont General Assembly, which was signed into law by Governor Jim Douglas on June 9, 2008. This Act, among other things, declares Vermont's groundwater to be a public trust resource and requires the state to manage groundwater in the best interest of all Vermonters. The new rules do not apply to drinking water supplied by public water systems in Vermont. Therefore, public water system operators, board members, and town officials do not need to worry about any additional permitting or reporting requirements for their public water systems resulting from the adoption of these rules. Also exempt are groundwater withdrawals for fire suppression and other public emergency purposes, domestic groundwater use, groundwater withdrawals for farming, dairy processors and milk handlers, and non-extractive geothermal heat pumps.

The new rules include the following reporting and permitting requirements:

Reporting: Those making groundwater withdrawals of more than 20,000 gallons per day (equivalent to about 14 gallons per minute), averaged over a calendar month, are required to file an annual groundwater report with the Vermont Agency of Natural Resources that includes the average daily rate of withdrawal from each existing source.

Permitting: On and after July 1, 2010, a groundwater withdrawal permit is required for new groundwater withdrawals for commercial, industrial, bottled or bulk water uses of more than 57,600 gallons a day (equivalent to 40 gallons per minute) from any source. Additionally, a groundwater withdrawal permit is required for previously unpermitted withdrawals where the increase in withdrawal for commercial, industrial, bottled or bulk water uses is 57,600 or more gallons per day, or the withdrawal is increased by 25 percent or more over its existing withdrawal rate if already over 57,600 gallons per day.

In order to obtain a groundwater withdrawal permit, several requirements must be satisfied to demonstrate that the proposed withdrawal will not adversely affect existing uses of groundwater or other water resources such as streams, ponds, and wetlands. The rules are currently making their way through the administrative procedures process. Public hearings are scheduled for December 8 and 9, 2010 in Rutland and Montpelier. If you are interested in learning more about making comments on these rules, please contact Eric Hanson at the Vermont Rural Water Association.


VRWA Offers Water Board Training

Paula Jackson, Water Systems Specialist

Vermont Rural Water Association offers water board training to selectboards, prudential committees, home owners associations, and any other type of drinking water system board that would like to learn more about their water system. Water board members are expected to make very important decisions regarding their water systems. Vermont Rural Water Association can attend meetings, set up special sessions or whatever works best for board members. Board members are usually volunteers and have job responsibilities, family etc. We understand that time is very valuable and very hard to come by.

We can flex our time to your schedule and provide training that will help board members to make better educated decisions regarding their water systems. We can provide training that is geared towards your specific needs.

Some topics of interest: drinking water regulations and requirements, financial planning, budgeting, how your water system operates, how we can better help our water operator, liabilities, and general board member responsibilities. Vermont Rural Water Association can also provide your water board with educational resources that they can work on when time allows.


Identifying Illicit Wastewater Discharges

Dave Braun, Water Quality Scientist, Stone Environmental Inc.

(Note from Wayne Graham VRWA Wastewater Specialist: in the past few years I have run into situations where identifying suspected wastewater was not always easy; a simple bacteria test is not always sufficient. Then I met Dave Braun! Dave has taken wastewater identification to a new level. I asked him to write this article to assist others in our field.)

Raw sanitary wastewater is easy to identify. But what if wastewater leaks from a sewer line and becomes diluted with groundwater, which is then intercepted by a stormdrain and discharged to a river; can we detect it then? Possibly, given the right test conditions, dogged persistence, and some luck.

My name is Dave Braun and I am a water quality scientist at Stone Environmental in Montpelier. For the last three years I've been sleuthing for sanitary wastewater and other contaminated flows in stormwater drainage systems in many Vermont towns. Most of the projects have been funded by the Agency of Natural Resources, Center for Clean and Clear. In most towns we've found one or more sources of wastewater entering stormdrains which are discharging to streams. On average we find dry weather flows in half the outfalls we assess and evidence of wastewater in 5% of them. We've also found petroleum contaminated groundwater from contaminated sites (former industrial sites, gas stations, a town garage), contaminated discharges from industrial facilities, and municipal tap water leaks.

We typically sample at stormdrain outfalls and at selected catchbasins and manholes during dry weather, when illicit discharges and other contaminated flows are not diluted by stormwater. The first step is to describe the condition of the discharge point and any dry weather flows. The nose is a sensitive detector, and I encourage everyone working on these assessments to use theirs as best they can. Samples are then collected for analysis of ammonia, electrical conductivity, and fluoride, assuming the municipal water supply is fluoridated. At every flowing outfall and in selected catchbasins and manholes, cotton pads enclosed in plastic mesh are secured in the flow stream, for detection of optical brighteners, which are fluorescent whitening agents (dyes) added to most laundry detergents. These are left in place for about a week, rinsed, dried, and viewed under a long-wave fluorescent lamp. Fluorescence usually indicates presence of laundry detergents, although oil can cause false positive results.

When test data suggest wastewater contamination, we return to collect samples for E. coli and total phosphorus analysis. High E. coli levels are a strong indication of wastewater contamination, although even apparently uncontaminated dry weather flows can have elevated E. coli levels. In fact, none of the tests we conduct can definitively differentiate between diluted wastewater sources and uncontaminated stormwater or groundwater.

Because no single test we perform provides definitive data, we take a weight of evidence approach in interpreting the data to determine which dry weather flows are likely to be contaminated. This determines where we conduct further investigations. Here are some rules of thumb we've developed in interpreting water quality test data, to distinguish between wastewater contamination and non-contaminated flows, along with potential interferences and other considerations:

Test Benchmark Remarks
E. coli >= 400 E. coli/100 mL Undiluted municipal wastewater will generally have E. coli levels an order of magnitude higher than this benchmark. Pet waste and wildlife sources can also cause elevated E. coli levels.
Ammonia >= 0.25 mg/L In the absence of other wastewater indicators, follow-up investigation is performed when the ammonia concentration is 0.5 mg/L or higher. If other wastewater indicators are present, the 0.25 mg/L benchmark is used. Decomposing vegetation under anoxic conditions can release ammonia to water, which can be misleading.
Optical brightener presence Presence usually indicates contamination by sanitary wastewater or washwater. Exposure of the test pad for 5-10 days means that diluted and intermittent discharges may be detected. Unfortunately, oil fluoresces at the same wavelength as optical brighteners.
Fluoride or total chlorine >= 0.3 mg/L Fluoride is more stable than chlorine and is therefore preferred for detection of wastewater and tap water. Chlorine may be used if the municipal water supply is not fluoridated. Municipal tap water typically contains 1-2 mg/L fluoride. Natural fluoride levels in groundwater in Vermont rarely exceed 0.1 mg/L. The fluoride test is subject to interference by dissolved iron.
Specific conductance >600 μS/cm Specific conductance is not a reliable indicator of wastewater contamination. Road salt and metals from pipe corrosion often result in levels in the 1,000-10,000 μS/cm range. However, flows contaminated with wastewater generally have specific conductance above 600 μS/cm.

The hardest part comes after dry weather flows have been assessed and the sources of contaminants have been isolated to segments of the stormwater drainage systems to the best of our ability. After the water quality testing comes the "find and fix" stage, where the accidents of plumbing and failures of infrastructure are hopefully revealed and corrected. Certain communities, notably Montpelier, have investigated the sources of contaminants using their staff and resources. Using data collected by my team, Montpelier located and eliminated several direct sanitary wastewater connections to stormwater drainage systems through closed circuit television inspection and dye testing. Many other communities lack the resources or skills to take on the investigation work themselves, and it is here that we've partnered with Vermont Rural Water Association (VRWA) to assist them.

Wayne Graham of VRWA has been a great partner in the investigation stage. With Wayne, Stone Environmental has smoke tested, dye tested, and camera-inspected pipelines for the towns of Swanton, Enosburg Falls, North Troy, and Richford. Wayne has the tools and the knowledge to use them, as well as good relationships with operators throughout Vermont. At times the investigations prove inconclusive; for example, the water quality data suggest a real problem but we cannot see the problem with the camera. In several instances we have nailed the problem though, such as the time in North Troy when we tracked washwater back to an improper connection in a house basement. We look forward to working with Wayne and VRWA again on upcoming projects.

Detecting illicit discharges and finding and fixing them is a field science. As we practice this science, we refine our methods and our ability to correctly interpret the data improves. In the future we expect to perform water quality tests that provide more definitive information than many of the current tests. We are particularly interested in definitive tests for human wastes, including tests for pharmaceuticals (including acetaminophen and ibuprofen), caffeine, and fecal steroids. At this time, these exotic tests are prohibitively expensive.

As method development continues, we expect to be able to use these tests, and others, to help Vermont communities identify longstanding sources of water pollution.

Exciting and Challenging Times

Shaun Fielder, Executive Director

A number of us from VRWA were lucky enough to attend National Rural Water Association's WaterPro conference in New Orleans in late September. Louisiana's Lieutenant Governor Scott Angelle offered comments at the opening. Mr. Angelle noted, "Our national success depends on all those decisions we make in regards to energy, environment, and economy. Balanced decisions and good management in these areas is required." Mr. Angelle's comments were right on target and as he concluded, I thought of the situation back home on energy, environment, and economy.

In Vermont, energy is a concern for all of us-the future of Vermont Yankee is unknown and a license extension beyond 2012 is definitely in question. Recognize a closure will significantly impact all our electric rates while a transition to alternative sources and greener forms of energy takes place. Fortunately there are some great opportunities available now on efficiency initiatives, so do take advantage of them (see Dmitri Hudak's and Amy Rubin's articles in this issue).

On the environment, all of us are working double duty to keep up with the standards of the Safe Drinking Water Act and Clean Water Act. Efforts continue to reduce impacts caused by excessive stormwater runoff and non-point source pollution.

Our economy has stabilized compared to last year at this time but there still is room for significant improvement. With the Vermont state budget showing a deficit of $112 million dollars for the next fiscal year, the upcoming legislative session will be challenging for all involved.

For water and wastewater facilities, the aging infrastructure and need for continued improvements is a priority. The stimulus funding has been obligated, but systems do have access to some excellent financing opportunities; financing rates are at their lowest levels in a generation. If you can believe it, some systems have adequately saved and are prepared to fund improvements without taking out a loan or receiving a grant, all should be striving for this.

To address the challenges noted above, all of us need to continue to advocate for our sector. You need to insure revenues properly cover the expenses needed to operate your system. Full cost pricing has to be part of the budgeting process moving forward.

To end his presentation, Lieutenant Governor Angelle said it best; "We all will persevere and it is a matter of tightening up the belt and keep on trying." Good advice for all of us, stick to it and keep plugging away. Happy Holidays to all of you, I wish the best to you and your family members.


Limited-Time Higher Rebates for Energy-Saving Lighting

Amy Rubin, Efficiency Vermont

A special, higher rebate is being offered by Efficiency Vermont through the end of December 2010. The rebate covers 50-90% of the cost of energy-saving lighting that is purchased and installed to replace T12 fluorescent lighting in 2010. This is a greatly increased rebate amount, put in place to help offset the costs associated with upgrading this equipment.

"In addition to this rebate information it's useful to know that, starting in 2012, high-energy T12 lighting will no longer be manufactured due to federal legislation," says George Lawrence of Efficiency Vermont. "That means a time will come when replacement lighting won't be available for burned out T12s. Because it will be necessary to replace T12s eventually, it makes sense to do it now, to take advantage of this year's significantly higher rebates, save on the upfront cost, and then get a quicker payback from energy savings."

Efficiency Vermont-recommended lighting uses 36-56% less energy than T12s and can last 1.5 times as long, lowering future replacement costs and associated maintenance time. Energy-saving lighting provides better-quality illumination and operates cooler, which can mean less heat in a facility during the summer.

How do you know if your fluorescent lights are T12s? According to Lawrence, "T12s are fatter. They're 1.5 inches in diameter.

Efficient tubes, such as High Performance T8s, are one inch in diameter." For more information on T12 replacement-lighting upgrades and rebates, see the facts about Efficiency Vermont's "newLIGHT" program at www.efficiencyvermont.com/newlight.

Efficiency Vermont also has recently expanded its list of LED (light emitting diode) lighting products that are eligible for rebates. Included in the list are LED wall packs for outdoor use. Long-lasting, low-energy LEDs can reduce costs for electricity, maintenance, and lighting replacements. LED quality can vary among manufacturers; to see a list of Efficiency Vermont-recommended, high-quality LEDs and to obtain a downloadable rebate application, visit:

Letters

Brandon Fire District No. 1
58 Franklin Street
Brandon, Vermont 05733

October 13, 2010

Dear Shaun,

Brandon Fire District No. 1 has been assisted by Vermont Rural Association employees for many years. In my time here, we have received aid form the following people: Elizabeth Walker, Jay Matuszewski, Shaun Fielder, Brent Desranleau, Paula Jackson, Eric Peterson, Aaron Perez and Eric Hanson. There are numerous others who have provided us with their expertise in training sessions. This letter is to thank you and your staff for the exemplary service that you provide. Your organization has been an invaluable resource to us.

I have been water system operator since 1997 and have encountered many situation that have required your assistance. With over 1100 connection and being the only employee, my job can sometimes be a bit overwhelming. It is comforting to know that we can make a phone call and help is on the way.

A special thank you goes out to Aaron Perez who has provided us with many hours of technical expertise. He has come to ur aid at all hours of the day and night line locating, doing leak detection and troubleshooting problems. Without his service, it would be difficult to complete these projects and situations in a timely, efficient and cost effective manner.

Recently, Eric Hanson has been working with us to complete out petition for Class 2 groundwater designation. His expertise in source protection has provided us with a much better understanding of our groundwater supply.

The Prudential Committee and water customers of Brandon Fire District No 1 are sincerely grateful for the wonderful resource that you provide us. Thank you again.

Sincerely,

Raymond Counter
Water Superintendent
