So trying to get that consolidation, one single set of documents, combining reviews around endangered species with NEPA reviews is really important.

因此，将濒危物种审查与《国家环境影响评估法》（NEPA）审查结合起来，尝试进行整合，形成一套文件，这确实非常重要。

The longest is really the right-of-way permit where the median length is nine years and then we have others, such as Environmental Impact Statement on the NEPA that takes about 3.5 years as a median.

耗时最长的是通行权许可证，中位数为 9 年，然后我们还有其他项目，如国家环保局的环境影响声明，中位数约为 3.5 年。
