Business. Landlord acknowledges that it is not the intent of this Section 30 to prohibit Tenant from using the Premises for the Permitted Use. Tenant may operate its business according to prudent industry practices so long as the use or presence of Hazardous Materials is strictly and properly monitored according to all then applicable Environmental Requirements. As a material inducement to Landlord to allow Tenant to use Hazardous Materials in connection with its business, Tenant agrees to deliver to Landlord prior to the Commencement Date a list identifying each type of Hazardous Materials to be brought upon, kept, used, stored, handled, treated, generated on, or disposed of from, the Premises and setting forth any and all governmental approvals or permits required in connection with the presence, use, storage, handling, treatment, generation, Release or disposal of such Hazardous Materials on or from the Premises (“Hazardous Materials List”). The Hazardous Materials List shall not be required to include janitorial supplies, office products such as ink and ink printer cartridges, over-the counter lubricants, paint, plaster, adhesives, and similar building maintenance products, food waste, commercial garbage or domestic sewage, all in volumes not to exceed those typically found in comparable buildings in the I-270 corridor in Montgomery County, Maryland, unless the generation, storage, or disposal of a particular material is regulated under applicable Legal Requirements. Tenant shall deliver to Landlord an updated Hazardous Materials List at least once a year and shall also deliver an updated list before any new Hazardous Material is brought onto, kept, used, stored, handled, treated, generated on, or Released or disposed of from, the Premises. Tenant shall deliver to Landlord true and correct copies of the following documents (“Haz Mat Documents”) relating to the use, storage, handling, treatment, generation, Release or disposal of Hazardous Materials prior to the Commencement Date, or if unavailable at that time, concurrent with the receipt from or submission to a Governmental Authority: permits; approvals; reports and correspondence; storage and management plans, notice of violations of any Legal Requirements; plans relating to the installation of any storage tanks to be installed in or under the Project (provided, said installation of tanks shall only be permitted after Landlord has given Tenant its written consent to do so, which consent may be withheld in Landlord’s sole and absolute discretion); all closure plans or any other documents required by any and all federal, state and local Governmental Authorities for any storage tanks installed in, on or under the Project for the closure of any such tanks; and a Surrender Plan (to the extent surrender in accordance with Section 28 cannot be accomplished in 3 months). Tenant is not required, however, to provide Landlord with any portion(s) of the Haz Mat Documents containing information of a proprietary nature that, in and of themselves, do not contain a reference to any Hazardous Materials or hazardous activities. It is not the intent of this Section to provide Landlord with information that could be detrimental to Tenant’s business should such information become possessed by Tenant’s competitors.

Landlord acknowledges that it is not the intent of this Article to prohibit Tenant from operating its business for the Permitted Use.
