Landlord environmental disclosure in commercial lease?
I'm looking through a commercial lease I want to sign, and there is an addendum at the back that says the following. Should I be concerned, or is this just a legally-mandated super-cautious notice?:

*"Environmental, Landlord has disclosed and Tenant hereby acknowledges that the property adjacent to the subject property was cited by a governmental agency for an environmental issue. In response to this, Landlord had the subject property tested by way of air sampling. The results of the air sampling test show that the air quality at the subject property is acceptable. Landlord will provide Tenant with a copy of the air sampling test and results so that Tenant, at its option, can review said report with a professional of their own choosing. Further, Tenant agrees that Landlord, upon providing reasonable notice, shall be able to take air samples at the subject property twice a year to make sure that the property is free and clear of any environmental issues."*

EDIT: Thanks for the feedback. I had already asked for the docs. The broker told me that no one had ever asked for more information before me (??)
