Background: The Greater Baldwin Hills Alliance (GBHA) is a collaborative effort of Community Health Councils, the City Project, neighborhood associations and block clubs. The alliance formed after Plains Exploration and Production (PXP) announced plans to expand their drilling operations in Baldwin Hills by 1,000 new wells. GBHA was formed to provide a forum for the impacted communities to review the draft Environmental Impact Report (EIR) and develop appropriate administrative, regulatory and legislative remedies.
