Hi,
I am creating the non-point oil gas emissions based on the 2017 platform. I got an error message showing 672, 697 6831, 6832 and 6833 surrogates are missing. The resolution I am running is different from EPA’s and I already generated my own surrogates using the pg\_tool and scripts from: [NEI 2017/2016v2 Platforms - Google Drive](https://drive.google.com/drive/u/0/folders/1tQViUa6b_GAVxgK4hG60ZuWDlSzS-omw)
But it looks like the missing surrogates are not in the speciation file. I saw a post about 6831-6833 surrogates: [Spatial Surrogate codes 6831, 6832, and 6833 - Spatial Allocator - CMAS CENTER FORUM](https://forum.cmascenter.org/t/spatial-surrogate-codes-6831-6832-and-6833/2179). Is there information about 672 and 697 surrogates that I can refer to?
Best
Wei

Never mind! I found them in the 2016 platform instead.
