I couldn't find specific information about a nonprofit organization named Mid Atlantic Propane Research & with the EIN 510387695. The search results primarily mention the Mid-Atlantic Propane Gas Association (MAPGA), which does not match the requested organization. Therefore, I cannot write an article based on the provided details. If you have more information or a different query, please let me know.
