Facts:
July 2017: NR submitted CEMP to Lambeth
Aug 2017: Rachel Heywood's objection letter, referred to in the Buzz article
Sept 2017: NR submitted revised CEMP to Lambeth
Dec 2017: NR submits another revised CEMP to Lambeth
Dec 2017: NR's CEMP approved by Lambeth.
So, it looks like there were at least two rounds of revisions to the submitted CEMP before Lambeth approved it, both of those revisions subsequent to the objections submitted by Rachel Heywood (and others).
You can read the officer's report, which gives details of all objections, and responses to them, here:

The approved CEMP is here:

When I saw the stuff about dust masks, I thought, she's probably read something in the CEMP mentioning dust masks, a bog standard requirement within building sites, and interpreted that as indicating some kind of unusual threat or danger to the public. That seems to be the case; here is the response on that point in the report.
Is Network Rail yet to address environmental concerns brought up by objectors with little knowledge of normal construction procedures? No they are not.
And by the way, if Rachel Heywood and Brixton Buzz are so worried about air quality, I wonder why they both supported the campaign to quash attempts to reduce motor traffic through Loughborough Junction. The primary and persistent danger to people's health as far as air quality is concerned comes from motor traffic, not building sites.
