Last week the Montgomery County Circuit Court Judge Terrence McGann struck down the county's ban of nonessential pesticide usage on private and public property. The Judge issued a summary judgment in favor of the plaintiffs; lawn care companies and private property owners who opposed the 2015 county measure. The ban, Bill 52-14 would have gone into effect Jan. 1, 2018 and would have banned the ornamental use of pesticides including Roundup and 2,4 D as well as hundreds of others.
Bill 52-14 restricted the application of pesticides on County-owned and private lawns down to 100 square feet. The law included all pesticides classified as "Carcinogenic to Humans" or "Likely to Be Carcinogenic to Humans" by the U.S. EPA; all pesticides classified by the U.S. EPA as "Restricted Use Products;" all pesticides classified as "Class 9" pesticides by the Ontario, Canada, Ministry of the Environment; all pesticides classified as "Category 1 Endocrine Disruptors" by the European Commission; and any other pesticides that are determined not to be critical to pest management in the County. Pesticides, including herbicides, insecticides, fungicides, and rodenticides, used to simply prevent blemishes and other imperfections on private and public lands are banned.
In his opinion Montgomery County Circuit Court Judge Terrence McGann said the county ordinance conflicted with state laws regarding pesticides, which would have pre-empted the county’s ability to pass pesticide regulations. Stating in the opinion: “The Ordinance prohibits the use of registered pesticide products that Maryland law permits, and in doing so, it simultaneously undermines the express purpose of State law to promote uniformity between Maryland pesticide requirements and those adopted by EPA and other states. The Ordinance prohibits and frustrates an activity intended to be permitted by State law.”
Judge McGann ORDERED that Plaintiffs’ Motions for Summary Judgment GRANTED; and further ORDERED that Bill 52-14 as it regards the use of pesticides on private property, shall not take effect, and Plaintiffs are entitled to permanent injunctive relief from the enforcement of these sections.
The Montgomery County ban on cosmetic use of herbicides and pesticides was intended to protect children based on their belief that children may be more at risk of developing health problems from pesticides because:
• Their activities lead to more exposure e.g., playing in the grass, putting their hands or toys in their mouths.
• They are closer to the ground and breathe in higher amounts of pesticides.
• Proportional to their weight, they breathe in more air and consume more food and drink than do adults.
• Their immature metabolic systems cannot break down toxins as effectively as adults.
• Their bodies are rapidly growing and developing and potentially impacted more strongly by endocrine disruptor effects.
With the exception of nitrogen, there has been no direct evidence linking pesticides to diseases in humans. Though, an increasing number of health and environmental groups are claiming that these chemicals do indeed impact human health. A wide range of chemicals are used to treat everything from pests to mold in household gardens. One of those is 2, 4-D, used by cereal crop producers and commonly found in household weed killers. It has been the subject of an extensive study by Health Canada which determined that, when used properly, it is safe. Organizations like the Sierra Club and the Canadian Cancer Society, which strongly support a ban on cosmetic use of pesticides and herbicides, disagree. However, no specific research linking the currently used ornamental pesticides to disease in humans was found.
The only documented study to find a disease link to 2,4-D was done in the United States, a 1991 National Cancer Institute study examined dogs whose owners' lawns were treated with 2,4-D four or more times per year. The study found those dogs had double the risk of developing canine malignant lymphoma than dogs whose owners do not use the herbicide.
In addition, glyphosate (N-phosphonomethylglycine), the active ingredient in the herbicide Roundup and the most popular herbicide in use today in the United States was labeled a probable carcinogen by the International Agency for Research on Cancer, IARC, in 2015. Americans spray an estimated 180-185 million pounds of the weed killer, on their yards and farms every year. All the acute toxicity tests have found that glyphosate is nearly nontoxic to mammals; however, there have been for some time a minority of scientists and experts who believes that glyphosate may be more toxic than is claimed and pushed for additional studies impacts to human health from low level constant exposure to glyphosate.
