Re: Friends of Casco Bay Testimony in Opposition to LD 1853: An Act To Ensure the Safe and Consistent Regulation of Pesticides throughout the State by Providing Exemptions to Municipal Ordinances That Regulate Pesticides

Dear Senator Davis, Representative Martin, and Distinguished Members of the State and Local Government Committee:

Please accept this letter as the testimony of Friends of Casco Bay in opposition to LD 1853: An Act To Ensure the Safe and Consistent Regulation of Pesticides throughout the State by Providing Exemptions to Municipal Ordinances That Regulate Pesticides. Friends of Casco Bay is a marine stewardship organization formed over a quarter century ago to improve and protect the environmental health of Casco Bay. Our work involves education, advocacy, water quality monitoring, and collaborative partnerships.

A year ago we submitted testimony similar to today’s testimony, opposing LD 1505: An Act To Create Consistency in the Regulation of Pesticides[1], a bill that would have eliminated municipal Home Rule to pass or implement pesticide-related ordinances. Although LD 1853 differs from LD 1505 by not explicitly referring to Home Rule, it implicitly guts it. LD 1853 provides that municipal pesticide ordinances cannot apply: (1) to commercial applicators and spray contracting firms or (2) to private applicators when the private applicators are producing agricultural or horticultural commodities. Horticulture means “the science and art of growing fruits, vegetables, flowers, or ornamental plants.”[2] Horticulture is: “[t]hat branch of agriculture concerned with growing plants that are used by people for food, for medicinal purposes, and for aesthetic gratification.”[3]

LD 1853 in essence removes the right of municipalities to pass pesticide ordinances for virtually any purpose. No ordinance can apply to commercial applicators. Nor can an ordinance apply to home applicators for basically any conceivable purpose, including weed-free lawns maintained for “aesthetic gratification.” For this reason, we respectfully request that this Committee unanimously recommend that LD 1853 ought not to pass, the same recommendation that it made for LD 1505.

PESTICIDES IN CASCO BAY

Our previous testimony, attached as Exhibit A, details the sampling Friends of Casco Bay conducted to detect the presence or absence of pesticides in stormwater that flows into Casco Bay. In summary, over 8 years, our research identified 10 different pesticides at 14 locations around the Bay. None of the pesticides are listed as safe for use in marine environments. For example, these six toxic pesticides were detected:

2, 4-D: banned in five countries, this herbicide is toxic to aquatic invertebrates and may be linked to non-Hodgkins lymphoma in humans.

Clopyralid: this herbicide has been linked to birth defects in animals.

Diazinon: banned from being sold to U.S. consumers but still legal for use, this insecticide has a high aquatic toxicity and is linked to reproductive problems.

Dicamba: found in groundwater throughout the U.S., this herbicide is toxic to fish and zooplankton.

MCPP: along with 2, 4-D, this herbicide is in the same family of chemicals as Agent Orange and is highly toxic to bay shrimp.

Propiconazole: this fungicide is a possible carcinogen.

Consistent with our mission to improve and protect the environmental health of Casco Bay, we strongly believe these substances should not be discharged into our marine waters.

MAINE MUNCIPAL PESTICIDES ORDINANCES

The Maine Constitution grants Home Rule to municipalities.[4] Home Rule allows municipalities to exercise any power or function that the Legislature confers upon them, and that is not denied expressly or by clear implication.[5] With respect to pesticide ordinances, the Legislature requires a municipality to notify the Maine Board of Pesticide Control (BPC) when it intends to adopt an ordinance. In turn, the BPC must maintain a list of all municipal ordinances that specifically apply to pesticide storage, distribution or use.[6] Municipalities adopt ordinances through considerable public process.[7] For example, Friends of Casco Bay’s Executive Director, Cathy Ramsdell, served for nearly a year on a task force that helped Portland shape its recently enacted pesticide ordinance.[8]

As a result of this very thoughtful process, 29 of Maine’s nearly 500 municipalities have enacted ordinances that narrowly restrict pesticide use to meet local needs.[9] It should be noted that none of these municipal ordinances out-right ban the use of pesticides. Here are some examples relevant to Casco Bay:

Brunswick prohibits use or storage of most pesticides other than for households and agriculture within the aquifer protection zone. The town also prohibits aerial applications other than public health applications performed under the auspices of the Town or State.  Exceptions may be approved by Codes Enforcement Officer.

Harpswell prohibits the use of the insect growth regulators (IGRs) diflubenzuron and tebufenozide and the aerial application of all IGRs and any insecticide whose product label indicates that it is harmful to aquatic invertebrates. The town also restricts the use of neonicotinoid insecticides.

New Gloucester requires application to be consistent with DCAF standards.

Portland’s recently enacted ordinance will restrict the use of synthetic pesticides for all public and private turf, landscape, and outdoor pest management activities. The ordinance takes effect for City property on July 1, 2018 and for private property on January 1, 2019. There are provisions for emergency exemptions.

South Portland curtails the use of pesticides for turf, landscape and outdoor pest management.[10]

Research revealed no legal challenges to these ordinances. They stand as a proper application of Home Rule and as excellent examples of municipalities crafting more protective regulation than federal and state law to protect the health of local residents, natural resources, and environmental concerns. LD 1853 should not be allowed to eviscerate this proper and necessary exercise of Home Rule.

For the reasons set forth above and in our prior testimony, we reiterate our request that this Committee unanimously recommend that LD 1853 ought not to pass.

Respectfully,

Ivy L. Frignoca

Spring starts early in Casco Bay!

Our Continuous Monitoring Station chronicles the rise and fall of microscopic blooms in Casco Bay. This graph of chlorophyll fluorescence tells us that the spring bloom of phytoplankton beneath the ocean happens well before plants on land emerge from beneath the snow.

 

It may be hard to believe if you have spent any time outside this chilly winter, but spring likely has sprung in the waters of Casco Bay.

By January, the lengthening daylight has jumpstarted the growth of phytoplankton, the single-celled plants that are the foundation of the ocean food web. Like plants on land, they respond to increasing sunlight by bursting into bloom. By mid-February, daylight has increased by over an hour since December 21st, and the phytoplankton are flourishing.

Last January, 2017, there was an early bloom of phytoplankton in Casco Bay. How do we know? Friends of Casco Bay maintains an underwater sentinel that collects information about the water of the Bay every hour, 24 hours a day, 365 days a year. It is our Continuous Monitoring Station.

We will soon be crunching the January-February 2018 data, looking for confirmation of this year’s phytoplankton bloom.

A modified lobster trap houses a carbon dioxide sensor and a data sonde, electronic devices that continually take the pulse of the Bay. Together, they provide evidence of how our coastal waters may be changing over time. This long-term monitoring station, fondly known as “the Cage of Science,” is anchored just above the sea floor off Cousins Island in Yarmouth.

We now have over a year of hourly data on oxygen levels, carbon dioxide, pH (the level of acidity of the water), salinity, temperature, water clarity, water depth, and chlorophyll fluorescence, a measure that provides an estimate of phytoplankton abundance. Chlorophyll is the green pigment in plants that traps the energy of the sun for photosynthesis.

Phytoplankton provide food for the smallest zooplankton. These tiny floating animals are eaten by larger zooplankton, such as copepods, shrimplike creatures. Both phytoplankton and zooplankton are at the mercy of the currents, winds, and tides.

The data from the Continuous Monitoring Station documents the changes in the water’s chemistry as a result of these blooms. The net positive effect in Casco Bay over the course of the spring season is more oxygen and less acidic water, thanks to those early-blooming phytoplankton.

Beyond Casco Bay, in the Gulf of Maine, a circular current called a gyre distributes marine life around the Gulf. The gyre transports phytoplankton to where zooplankton are hatching, just in time to feed emerging copepods, which in turn feed baby fish, clams, and other sea creatures.

Success in the ocean food web, like in much of life, depends on being in the right place at the right time.

Our Continuous Monitoring Station has been in place for about a year and a half, too soon perhaps to provide data that might indicate whether or not Casco Bay’s food web is changing. Still, every hour and every day, our cage of science is building a more complete picture of the seasons beneath the Bay, giving us insight into how climate change may alter the food web of our coastal water in years to come.

Thank you to funders of this project, including Casco Bay Estuary Partnership, Davis Conservation Foundation, Horizon Foundation, Schwartz Family Fund of the New Hampshire Charitable Foundation, and WEX. We also thank our Members and the many donors, local businesses, and foundations that give us operational support to do our work each year.

Keeping you up to date as we keep an eye on the Bay

Casco Bay, like ocean water around the world, is changing and changing quickly.

We want you to know that we have changed our volunteer Citizen Stewards Program and our staff-led Water Quality Monitoring efforts in order to stay on top of the science of how the Bay may be changing.

When our organization started in 1989, no one knew the health of the Bay. That was the question we were asked—“How healthy is Casco Bay”—and that is what our first quarter-century of monitoring has enabled us to address.

Thanks to the data that hundreds of our volunteer Citizen Stewards have helped us collect over the past 25 years, in addition to data collected by our staff, we can identify where regions of the Bay are challenged, and where, generally speaking, the Bay is healthy. The snapshots of data volunteers collected are a key aspect of our Casco Bay Health Index and have been vital to our advocacy efforts. This 25-year data set has provided us with a solid foundation from which to launch this next phase of data collection.

Looking forward, our monitoring goals are to:

  • Understand how Casco Bay is changing with respect to climate change, ocean and coastal acidification, sea level rise, and other stressors
  • Conduct more intense data collection efforts in challenged regions of the Bay to try to understand why water quality is so poor, in places such as Portland Harbor and the mouth of the Harraseeket River
  • Involve more volunteers in our efforts to keep Casco Bay blue. While we are utilizing more technology to help us achieve our first two goals, technology will never replace the connections, energy, visibility, and goodwill that volunteers like you provide as ambassadors for the Bay.

In order to meet these goals, we are now monitoring Casco Bay through these four ways:

  1. Our Continuous Monitoring Station collects hourly data to help us address the question “How is Casco Bay changing?” We launched this station more than a year ago, and we are excited about how much we have learned about the Bay in a short time. We intend to keep this Station operating in perpetuity.
  2. Using data sonde technology, our staff will continue to collect data at 12 legacy volunteer Citizen Steward sites—these sites were chosen as representative of regions around the Bay and include healthy sites, challenged sites, and those in between. We think of this monitoring as “the Bay getting a checkup.” How are regions of the Bay doing? Are healthy areas remaining healthy? Are challenged areas continuing to show problems, or might they be improving?
  3. Using our Baykeeper boat, our staff will conduct more intensive efforts in challenged regions of the Bay. If you have seen our Health Index, you have seen that there are “red dot” areas. We are looking closer at those red dot areas and asking, “what may be causing the trouble?” We began this work in 2017, as we conducted transects, from surface to bottom, and across regions, in Portland Harbor and in the Harraseeket River. We will continue to look intensively at these regions.
  4. Using volunteer citizen scientists, we will engage the community to help us collect data and observations on a changing Casco Bay. Our volunteer program is going through a large transition. We are significantly changing the time commitments required to become a citizen scientist, and we are changing the parameters that volunteers collect. We will be asking Citizen Steward Volunteers to collect new kinds of data and record observations on changes in Casco Bay.

In 2016, you may remember that we organized a citizen science “flash mob to Nab Nitrogen.” The event was an incredible success, signaling that there is a huge reservoir of goodwill from people who want to help protect the health of the Bay and are willing to do that in short bursts of data collection efforts. We learned that we can count on our community to help us grab vast amounts of data if we make sampling easier and reduce the time commitment.

For example, we are piloting having volunteers measure the color of our waters as a biological indicator. The general public often considers blue water to indicate healthy oceans and dirty-brown water to indicate polluted water. In fact, scientists attest to color being an excellent indicator of what is happening in our oceans. For more than a century, marine scientists have used the Forel-Ule scale to document the color of oceans and lakes.

The color of our water, measured by this scale, can be an excellent environmental indicator. By using a specially designed smartphone app and a secchi disk, volunteers can help us collect scientific data on the color and clarity of our waters. The protocols for this data collection are easy to follow, and the data helps address a question we often hear: “How is the Bay changing?”

We will also ask volunteers to help us observe and keep track of nuisance and harmful algal outbreaks, which have plagued our waters these past two summers.

By revamping our volunteer monitoring efforts, we have the opportunity to broaden our network of knowledgeable ambassadors for our coastal waters—and make strides in our understanding of the Bay.

In our experience, our volunteers are some of the most active, outspoken, and well-spoken members of our community. We look forward to engaging more volunteers than ever this year. The commitment of these volunteers will send ripple effects through towns around the Bay.

After a rainstorm, millions of gallons of polluted stormwater pour into Casco Bay.

Support of LD 178: An Act To Authorize a General Fund Bond Issue To Provide Jobs, Improve Road Infrastructure and Protect Water Resources

Re: Friends of Casco Bay Testimony in Support of LD 178: An Act To Authorize a General Fund Bond Issue To Provide Jobs, Improve Road Infrastructure and Protect Water Resources

Dear Senator Hamper, Representative Gattine and Distinguished Members of the Committee on Appropriations and Financial Affairs,

Friends of Casco Bay submits this letter in support of LD 178: An Act To Authorize a General Fund Bond Issue To Provide Jobs, Improve Road Infrastructure and Protect Water Resources. We respectfully request that the committee unanimously recommend that LD 178 “Ought to Pass.”

Friends of Casco Bay is a nonprofit organization committed to protecting and improving the water quality of Casco Bay. We have several thousand members and volunteers who rely upon Casco Bay for their livelihoods, recreation, and solace. For over a quarter century, we have monitored the health of Casco Bay and advocated for solutions that eliminate or reduce nonpoint source pollution (NPS) to the Bay.

NPS pollution occurs when rain or snowmelt flows over land, picks up contaminants, and drains into waterways. NPS pollutants can include contaminated sediments, petroleum products from roads, fertilizers, pesticides, and other pollutants. Nonpoint source flows are the largest source of pollution to coastal Maine waters, and Casco Bay receives significant loads of NPS pollution.

Between 2001 and 2009, we collected rainwater flowing directly into the Bay and analyzed the samples for pesticides. Our goal was to determine “presence” or “absence” of pesticides. Lab results identified 10 different pesticides in 14 locations around the Bay.

In 2014, we collected samples from the mouth of the Presumpscot River during a dry weather flow, a medium rain event, and an intense rain event. In comparison to the dry weather flow, the intense rain event delivered large loads of bacteria, suspended solids, and nitrogen. E.coli during dry weather was detected in trace amounts. Right after the intense rain event, E.coli measured 170 colony forming units (CFU) per 100 ml*. Total suspended solids (TSS) during the dry event measured 3.6 mg/L. After intense rain, TSS measured 60 mg/L**. Total nitrogen measured at .32 mg/L during dry weather and increased to .70 mg/L after the intense rain event.***

The photo below shows a stormwater plume draining into Casco Bay with its brown load of sediment and other pollutants.

“We do have issues when it rains,” Keri Kaczor, Maine Healthy Beaches Coordinator said in 2014. “We have a lot of water in Maine, with the rivers, the streams and the storm drains bringing pollutants from upland areas to the sea. When we have a wet beach season, we have problems.”****

LD 178:
This $5,000,000 bond will fund cost sharing of at least 50% on projects that correct downstream pollution issues through improved upstream stormwater management. Friends of Casco Bay supports this bond because, as our data show, Casco Bay is a downstream water that receives NPS pollution.

Most NPS pollution is not regulated under the Clean Water Act. Instead, Section 319 of the Act provides limited federal funding to reduce NPS pollution. That funding alone is insufficient. State funds must supplement it.

LD 178 fulfills that purpose; it provides funding to reduce upstream sources that negatively impact downstream receiving waters such as Casco Bay. Friends of Casco Bay respectfully requests that the Committee unanimously recommend that LD 178 “Ought to Pass.”

Thank you for considering our testimony.

Sincerely,

Ivy L. Frignoca

*E. coli is a specific species of fecal coliform bacteria. It is the best indicator of fecal pollution in fresh water. In
Maine, E. coli levels at designated swimming beaches should not exceed 104 CFU per 100 ml.

**Total suspended solids (TSS) measures the turbidity of the water. Suspended solids cause water to look milky or
muddy as light scatters from very small particles in the water.

*** For purposes of evaluating harmful impacts of nitrogen to marine waters, DEP considers .32 mg/L of nitrogen as
having the reasonable potential to negatively impact eelgrass habitat and .45 mg/L as having the reasonable potential
to negatively impact dissolved oxygen levels.

The looming question for the future— How is Casco Bay changing?

We see water itself as fundamental habitat. When water quality deteriorates, eelgrass, plankton, clams, and other marine creatures suffer. Thanks to our 25-year data set on water quality in Casco Bay, we now have a better overall understanding of the health of the Bay. We understand when and which areas of the Bay are likely to exhibit challenged water quality conditions.

Armed with this baseline data, we can now begin to address the question How is the Bay changing?—thus, the establishment last year of our first automated Continuous Monitoring Station. We will also continue to monitor selected sites at the surface, to supplement the historical data set compiled by our Citizen Stewards Program. And, we will look more intensively, using surface-to-bottom transects, at those regions of the Bay which present challenged conditions. New data and observations may help us begin to understand how climate change, excess nitrogen, and the changing chemistry of Casco Bay may be impacting the ocean food web.

Our Nabbing Nitrogen event in 2016 signaled to us that there is a huge reservoir of goodwill from people who want to help protect the health of the Bay and are willing to do that in short bursts of data collection efforts. We foresee new volunteer opportunities in this type of data collection, as well as in expanding other community service projects, such as coastal clean-ups, storm drain stenciling efforts, and issue-education events to inspire Champions for the Bay.

Citizen Steward volunteers will continue to be key to our organization as they help us move into this next phase of work to improve and protect the environmental health of Casco Bay. Casco Bay belongs to all of us, and this Bay is fortunate to have so many Friends.

What we have learned from 25 years of water quality data

Since 1992, more than 650 volunteers have gotten their hands wet in our Citizen Stewards Water Quality Monitoring Program, complementing the work of our staff scientists in assessing the environmental health of Casco Bay. This science is the foundation of much of our community engagement and advocacy efforts.

Volunteer Citizen Stewards measured dissolved oxygen, temperature, salinity, water clarity, and pH at nearly 40 shoreside sites on the same date and time on ten Saturdays from April through October, to create a simultaneous snapshot of surface conditions around the Bay.

Our staff scientists have monitored offshore at 10 stations, from surface to sea floor, aboard our research vessel, every month of the year.

The data allowed us to address these questions:

  • How healthy is the Bay?
  • Where are problem areas?
  • What influences the health of the Bay?

 

What we have learned

  • Casco Bay is generally healthy, compared with other estuaries.
  • Year after year, our data has identified Portland Harbor, the New Meadows embayment, and the mouth of the Harraseeket River as the most environmentally challenged areas in Casco Bay.
  • The healthiest regions of the Bay are Broad Sound, Maquoit and Middle bays, and the offshore waters near Halfway Rock.
  • By sampling both along the shore and offshore, we determined that land-based origins contribute significant sources of excess nitrogen.
  • The bottom water of the Bay has become more acidic, a worrying trend that mirrors what is happening worldwide.
  • Summer is lasting longer beneath Casco Bay. Water temperatures are staying warmer into the fall.
  • In order to better understand how the Bay is changing, we are increasing the frequency of data collection.

After a rainstorm, millions of gallons of polluted stormwater pour into Casco Bay.

Stormwater: the Largest Source of Pollution into Casco Bay

Presumscot River Creates a Brown Bay

MS4. Unless you are a civil engineer or a municipal public works director charged with dealing with discharge permits, you may not know that “MS4” stands for municipal separate storm sewer systems (called MS4 because “s” is repeated four times). An MS4 is a system of storm drains, pipes, or ditches that collect and carry stormwater, untreated, into our waterways (not to a sewage treatment facility).

To reduce stormwater pollution, the Clean Water Act requires larger cities and towns to develop an MS4 plan that includes six Minimum Control Measures: public education, public involvement and participation, illicit discharge
detection and elimination (finding and eliminating sources of contamination that improperly enter the pipes), construction measures designed to reduce stormwater pollution, post construction inspections to ensure compliance, and municipal pollution prevention practices.

MS4 permits for these plans must be renewed every five years. Casco Baykeeper Ivy Frignoca is participating in the stakeholder process initiated by Maine’s Department of Environmental Protection, as it drafts the next MS4 permit.
You may have noticed that storms are more intesne, and the pollutants that rainstorms are flushing into the Bay are increasing dramatically. After one heavy rainstorm, we found a wedge of polluted stormwater 18 feet deep floating on top of seawater in Portland Harbor. Ivy worries,“Imagine what it would be like for a fish trying to navigate through that toxic mix of oil and gas from city streets, pesticides, bacteria, and nitrogen pollution from sewage and fertilizers!”

Ivy says, “The goal is to improve water quality and reduce nitrogen inputs and other pollutants. Reviewing and commenting on drafts of the next MS4 permit gives us an opportunity to help reduce the impacts of the largest source of pollution into Casco Bay.”

Historic Agreement to Cut Nitrogen by 20-40%

Imagine if we could remove 500 to 1,000 pounds of excess nitrogen from the Bay each day. An historic effort by Portland Water District may do just that!

After nearly a year of work, the Portland Water District and Friends of Casco Bay developed an agreement aimed at reducing nitrogen pollution from sewage effluent. The collaboration helped the Maine Department of Environmental Protection (DEP) develop a 139-page,
five-year permit for the City of Portland’s East End Wastewater Treatment Facility, which is managed by the Water District, that will better protect water quality. The permit was issued on March 22, 2017.

The $12 million upgrade to the plant’s aeration system may help reduce nitrogen in the plant’s effluent waters by 500 to 1,000 pounds each day!

The aim is to reduce nitrogen loading in the discharges from the plant by 20-40% within five years. This is the first wastewater discharge permit in Maine to address nitrogen levels and is now a model for other communities.

A History of Our Work to Reduce Nitrogen in Casco Bay
In 2007, Friends of Casco Bay helped persuade the Maine Legislature to pass a law requiring the Maine DEP to establish a limit on how much nitrogen may be discharged into coastal waters. Instead of following the Legislature’s lead, DEP has chosen to limit nitrogen permit by permit in Casco Bay. This had led Friends of Casco Bay to work with DEP, municipalities, and businesses, to help set realistic limits on nitrogen in Clean Water Act discharge permits issued to sewage treatment plants and industrial facilities.

We are working with the City of Portland on its Combined Sewer Overflow Remediation Project that will help reduce
nitrogen-laden sewage overflows into the Bay.

Our pumpout boat removes raw sewage—another source of nitrogen—from the holding tanks of recreational boats and transports, for onshore disposal. Contact pumpout [at] cascobay [dot] org.

Our BayScaping program works with residents and municipalities to help keep fertilizers and pesticides from polluting the Bay. We present BayScaping Socials to help neighbors reduce the use of lawn chemicals. With our support, South Portland passed an ordinance to restrict pesticide use, with an assurance to tackle fertilizers next. Executive Director Cathy Ramsdell served on the Portland Pesticide Task Force as that city considers a similar ordinance.

Back Cove August 2nd, 2017

Our “Slime Watchers” Are Keeping an Eye on the Bay

Back Cove August 2nd, 2017
Friends of Casco Bay volunteer Deb Dawson took this algal bloom photo over Portland’s Back Cove this summer to document how much the green slime had spread.

If you have ever thought about buying a drone but could not figure out what to use it for, take a lesson from Deb Dawson, a professional photographer and one of our volunteer water quality monitors. This past summer, Deb took her talents to even greater heights—right over Back Cove in Portland with her new drone outfitted with a video camera.

Executive Director Cathy Ramsdell, who regularly walks Baxter Boulevard, had reported seeing green algae growth spreading across Back Cove. She says, “We know that nitrogen fertilizes green plants in the ocean just as it does on land. It would be great if we could determine what is causing this bloom – excess fertilizer? – stormwater runoff? – sewage discharges? – a lack of predators? – car and factory emissions? – or all of the above!”

Before launching her drone, Deb checked with the Portland Jetport to make sure the route she had scouted out would not interfere with the traffic pattern of landing and departing planes.

Deb’s images confirmed what Cathy had feared: the Cove was quickly becoming carpeted in green slime. An email alert went out to Friends of Casco Bay members and the news media.

Other “green slime” reports have come in from other parts of Casco Bay. Report excess green slime by emailing slimewatchers@cascobay. org. Take a photo and tell us the location, with coordinates and landmarks, if you can.
