As I understand current policy in the UK, brownfield land is any land that has previously been developed - industrial, commercial, residential. In the case of a residential site, there are presumably no land contamination issues and so no need for an EIA. Though I must admit I though an EIA was intended to look at the impact of a new proposal on the surrounding area rather than a study of legacy issues of the land itself.
