随着北美自由贸易协定（North American Free Trade Agreement）的通过刺激了经济增长，美墨边境沿线的重大环境基础设施需求预计将变得更加严峻。1993年，美国和墨西哥解决了这一问题，签署了一项双边协议，建立了两个新的相互关联的国际机构。边境环境合作委员会（BECC）审查并认证在国际边境100公里（62英里）范围内提出的环境基础设施项目。北美开发银行（NADBank）帮助开发BECC认证项目的融资，并充当贷款人。迄今为止，已有26个项目获得认证，其中14个项目获得了NADBank的直接资助。这些机构与公共和私人项目赞助者以及金融从业人员合作。 小型系统既有资格获得资助，以协助申请过程，也有资格获得项目，以发展其建设和运营新设施的内部能力。包括14个参考文献、表格和图表。

With the economic growth spurred by passage of the North American Free Trade Agreement, the significant environmental infrastructure needs along the US-Mexico border were expected to become more severe. In 1993, the US and Mexico addressed this concern, signing a bilateral agreement that created two new interrelated international institutions. The Border Environment Cooperation Commission (BECC) reviews and certifies environmental infrastructure projects proposed within 100 km (62 mi) of the international border. The North American Development Bank (NADBank) helps develop financing for BECC-certified projects and also serves as a lender. To date, 26 projects have been certified, with 14 projects receiving direct NADBank funding. The institutions work with both public and private project sponsors and financial praticipants. Small Systems are eligible both for grants to assist with the application process and for programs to develop their internal capacities for construction and operation of new facilities.
