The mandate, which has pinpointed Milford, Franklin and Bellingham, aims to clean up the Charles River, specifically the phosphorous found in the river from stormwater runoff.
"It's not that we don't view the public policy goal as worthy," Fernandes said. "What we don't think has been thought through is whether this is being implemented fairly."
The cost that comes along with the new mandate, an estimated $35 million to $60 million in Milford and an estimated $71 million in Franklin, is something that Fernandes said will hurt the towns.
With an additional cost to regulate stormwater, many businesses may choose to stay out of Milford, Franklin and Bellingham, creating unfair competition not only with bordering towns, but also towns in Rhode Island and Connecticut.
In addition, Fernandes said the towns' added cost in regulating the stormwater has the potential to place a tax burden on residents, creating even more of a disadvantage.
