Wynn Resorts is pushing back after Massachusetts’ Attorney General called for state environmental officials to deny the company a crucial environmental permit for its $1.7 billion casino project.

Friday’s correspondence from Healey to the state’s environmental affairs secretary contends that traffic issues surrounding the notoriously congested area around Boston’s Sullivan Square need to be addressed by Wynn before the permit is issued.

“If you approve the Casino without a long-term traffic mitigation plan, we may never get one”, she wrote.

Wynn Resorts last fall won approval from Massachusetts gaming regulators to build a casino on the site of a former chemical plant in Everett, near Boston. In July, Healey wrote a letter to Transportation Secretary Stephanie Pollack indicating that she had issues with a traffic study conducted by Wynn consultants.

The casino project, slated to be one of the largest private developments in the state’s history, would be located on approximately 30 acres of land previously used as an industrial area, and would include amenities such as a dining and entertainment complex. “After two-and-a-half years, and millions of dollars and thousands of pages of traffic analysis, we are ready to move forward with our Wynn-funded $10.9 million Sullivan Square package, which will mitigate the incremental traffic impact of our project”.

Wynn spokesman Michael Weaver stated Friday that the environmental and visitors assessment requires the corporate to “mitigate our visitors impacts, not clear up decades-long visitors points which pre-date our venture”. It is now over 10,000 pages of detailed proposals to deal with challenge impacts.

Already, Wynn has announced that it will subsidize MBTA Orange Line operations to the tune of $7.36 million over 15 years for improvements that will be in place when it opens its resort casino along the Mystic River.

In addition to Healey’s letter, Beaton has acquired at the least 18 written feedback and nearly 700 submissions despatched electronically, based on paperwork offered by the workplace. The electronic ones represent identical form letters speaking in favor of the Wynn project but signed by different people.

Boston and two nearby cities, Revere and Somerville, filed separate lawsuits challenging regulators’ decision to give Wynn the only casino license for eastern Massachusetts.
