The pace of cleanup at federal facility Superfund sites can be delayed when Federal Facility Agreement (FFA) parties continue disputes beyond the agreed-upon dispute resolution timelines specified in negotiated FFAs. However, because disagreements and disputes are fact-specific, a fluid rather than a one-size-fits-all process may at times be necessary. This September 2018, memorandum sets out principles clarifying and reinforcing the importance of adhering to agreed-upon FFA informal and formal dispute timelines. These principles support Recommendation 18 of the Administrator's Superfund Task Force Recommendations report, released on July 25, 2017.
