*Update to addenda issue ID# 100000296, originally posted 12/2/2009* Following this section, create a new section with the header "Design or Construction Phase Submittal" and insert the three tables below.

In the fourth row of the table, change "lists of ingredients with GreenScreen benchmarks" to "lists of ingredients with GreenScreen Benchmark or LT scores"

In the last sentence of the third paragraph, replace "also" with "not" so that the sentence reads: "Projects in the U.S. may not use this alternative compliance path."

Delete Figure 2. Example master plan project

Revise the sentence that begins with "Use the following steps..." and step 5, and also add a paragraph to the end of this section:

Revise step 5 and add a paragraph to the end of this section:

Detailed explanation regarding calculation of the percentile event using daily rainfall records can be found in EPA 841-B-09-001, December 2009, www.epa.gov/owow/nps/lid/section438.

Add "soil qualities" to the cell about plans, details, or cross sections:
"Plans, details, or cross sections depicting site conditions and GI or LID strategies, highlighting topography, soil qualities, direction of water flow, and area of site that each facility addresses"

Replace the definition of "native vegetation" with the following:
"a species that originates in, and is characteristic of, a particular region and ecosystem without direct or indirect human actions. Native species have evolved together with other species within the geography, hydrology, and climate of that region."
