Several environmental groups are threatening to sue coal producer Massey Energy Co. for what they claim are more than 12,000 violations of pollution laws.

The Sierra Club and several West Virginia groups said Monday they’ve given Massey a notice that gives the company 60 days to reach a settlement or face a lawsuit.

The groups claim Massey has continued with the same pattern of violations covered by a $20 million settlement with the Environmental Protection Agency two years ago.

Here is the Notice of Intent to Sue:
