The U.S. Department of Agriculture (USDA) approved hemp regulatory plans for Maryland and the Lower Sioux Indian Community on Thursday.

With this latest development, the total number of approved plans across states, territories and tribes is 55.

USDA has been signing off on hemp proposals on a rolling basis over the past year. Last month, it accepted plans from Minnesota, Tennessee and Puerto Rico.

“USDA continues to receive and review hemp production plans from states and Indian tribes,” the agency said in a notice.

While the agency released an interim final rule for a domestic hemp production program last year, industry stakeholders and lawmakers have expressed concerns about certain policies it views as excessively restrictive.

USDA announced in February that it will temporarily lift two provisions that the industry viewed as problematic. Those policies primarily concern testing and disposal requirements. The department declined to revise the THC limit, however, arguing that it’s a statutory matter that can’t be dealt with administratively.

Last week, two senators representing Oregon sent a letter to the head of USDA, expressing concern that testing requirements that were temporarily lifted will be reinstated in the agency’s final rule. They made a series of requests for policy changes.

Agriculture Secretary Sonny Perdue has said on several occasions that the Drug Enforcement Administration influenced certain rules, adding that the narcotics agency wasn’t pleased with the overall legalization of hemp.

State agriculture departments and a hemp industry association also wrote to Congress and USDA this week, seeking an extension of the 2014 Farm Bill pilot program for hemp to give states more time to develop regulatory plans to submit to the agency.

Meanwhile, the Food and Drug Administration (FDA) is still in the process of developing regulations for CBD. It sent an update on its progress to Congress in March, explaining that the agency is actively exploring pathways to allow for the marketing of the cannabis compound as a dietary supplement and is developing enforcement discretion guidance.

An FDA public comment period was reopened indefinitely for individuals to submit feedback on CBD regulations.

Last month, the White House finalized a review of FDA CBD and cannabis research protocols, but it’s unclear when or if the document will be released to the public.

Also last month, FDA submitted a report to Congress on the state of the CBD marketplace, and the document outlines studies the agency has performed on the contents and quality of cannabis-derived products that it has tested over the past six years.

Amid the coronavirus pandemic, hemp industry associations pushed for farmers to be able to access to certain COVID-19 relief loans—a request that Congress granted in the most recent round of coronavirus legislation.

However, USDA has previously said that hemp farmers are specifically ineligible for its Coronavirus Food Assistance Program. While the department initially said it would not reevaluate the crop’s eligibility based on new evidence, it removed that language shortly after Marijuana Moment reported on the exclusion.

Two members of Congress representing New York also wrote a letter to Perdue in June, asking that the agency extend access to that program to hemp farmers.

Hemp farmers approved to produce the crop do stand to benefit from other federal loan programs, however. The department recently released guidelines for processing loans for the industry.
