Virtual forum on bomb blasts being conducted in San Joaquin County

Editor, Manteca Bulletin,

The Livermore Lab, a federal nuclear weapons facility, operates a high explosive testing range, called Site 300, near Tracy. Manteca is downwind. 

The Lab proposes increasing the size and yield of open-air bomb blasts at Site 300 tenfold, from the 100 pounds currently allowed to 1,000 pounds of high explosive compounds per detonation. These blasts involve potential adverse impacts to our air quality. According to Lab data, there will be more than 100 hazardous chemical components in each detonation.

Recently, I brought this issue to the Manteca City Council. I am gratified they are looking into the Lab’s proposal. I have asked them to send a letter of concern.

As Manteca residents, we all have an opportunity to learn more about the proposed bomb blasts at a virtual community meeting. It will be held on Tuesday, Dec. 8, at 7:30 p.m. For details, visit

Phyllis McDonald,
