On February 28, a series of tornadoes damaged southern Missouri and killed three residents.
"I went to southern Missouri and saw the serious property damage to homes and businesses, and the places where Missourians lost their lives," Nixon said in a statement.
Nixon requested a disaster declaration on March 13 from the SBA, which would clear the way for financial assistance to Missouri residents and businesses affected by the severe storms and tornadoes, according to a news release issued by the governor's office.
If the SBA granted Missouri's request it would issue loans to homeowners, renters, businesses of all sizes and not-for-profit organizations to repair or replace real estate, personal property, machinery and equipment, inventory and business assets that have been damaged or destroyed.
FEMA denied the governor's request to declare 18 counties in Missouri major disaster areas on Monday. Local and state officials said the reason for the denial may because most of the structures damaged in the storms were insured.
Nixon said he was "disappointed" with FEMA's decision.
Nixon said the tornadoes and storms at the end of February caused heavy damage to homes and businesses across several Missouri counties, and that financial impact will be felt for some time.
The state is still recovering from the Joplin tornado in May 2011 that killed nearly 150 people and devastated the town.
“Even as we continue to work at the state level to ensure that communities have the critical resources, assets and personnel to rebuild and recover, I'm seeking this disaster declaration from the SBA to make this financial assistance available to help our citizens and businesses keep moving forward,” Nixon said in his statement.
Scott Holste, Gov. Nixon's spokesperson, said they did not know when SBA would respond to their request.
