Cross-Border Agreements Related to Emergency Response

Mexico and the United States have a binational Joint Contingency Plan.

In addition, numerous "sister cities" along the border have their own local, cross-border joint contingency plans. Within the geographical area covered by the Four-State Regional Workgroup, there are six pairings of U.S. and Mexican sister cities with such plans that explain how they would cooperate in the event of emergencies.
